Consider a category C of algebraic structures; the objects can be thought of as sets plus operations, obeying some laws. ) Wikipedia contains no definition. 18:11 Ngentot Pacar 3X Ronde Tanpa Jeda. Instances of std::function can store, copy, and invoke any CopyConstructible Callable target-- functions (via pointers thereto), lambda expressions, bind expressions, or other function objects, as well as pointers to member functions and pointers to data. Free Watch Nonton Streaming Video ABG Jilbab Putih nyepong crot di mulut Mesum Terbaru Bokep Indo XXX Online Download Gratis Kualitas HD. e. In context|computing|lang=en terms the difference between functor and function is that functor is (computing) a function object while function is (computing) a routine that receives zero or more arguments and may return a result. A book that I states that functions take numbers and return numbers, while functionals take functions and return numbers - it seems here that you are saying functors can take both 1) functions and return functions, and 2) take numbers and return functions. Monads (and, more generally, constructs known as “higher kinded types”) are a tool for high-level abstraction in programming languages 1. See also at idempotent monad – Properties – Algebras for an idempotent monad and localization. Given categories and , a functor has domain and codomain , and consists of two suitably related functions: The object function. function object implementing x + y. A functor is an object or structure that can be called like a function by overloading the function call operator (). The main goal of this post is to show how some of the main ingredients of category theory - categories, functors, natural transformations, and so on, can provide a satisfying foundation for the theory of graphs. In category theory, the coproduct, or categorical sum, is a construction which includes as examples the disjoint union of sets and of topological spaces, the free product of groups, and the direct sum of modules and vector spaces. The differential operator in calculus is a common example, since it maps a function to its derivative, also a function. Functions. In category theory, a branch of abstract mathematics, an equivalence of categories is a relation between two categories that establishes that these categories are "essentially the same". Maybe is a Functor containing a possibly-absent value:. To create a functor, we create a object that overloads the operator (). Such an invocation is also known as an "indirect. Proposition 0. Example #2: the fundamental group. function. Funcrot Website Dewasa Terlengkap, Nonton "Putri Lestari Hijab Binal. See also the proof here at adjoint functor. We also require that F preserves the structure (i. For example. 05:00. "Pasti dong bu,rendi gak mungkin ngajakin anisa macem-macem". Either and the pair or two-tuple are prototypical bifunctors, and the reason we link Functor and Bifunctor in this series is that Bifunctor provides the answer to some very. There are video recordings with those content: part 1, part II and part III. Usually the word functorial means that some construction of some sort is a functor. 1) The identity mapping of a category $ mathfrak K $ onto itself is a covariant functor, called the identity functor of the category and denoted by $ mathop { m Id} _ {mathfrak K } $ or $ 1 _ {mathfrak K } $. It shows how the generic function pure. The most general setting for a free object is in category theory, where one defines a functor, the free functor, that is the left adjoint to the forgetful functor. We don't have to think about types belonging to a big hierarchy of types. Functors are objects that behave as functions. Let’s say you want to call the different functions depending on the input but you don’t want the user code to make explicit calls to those different functions. ”. Methods. Moreover, not every concrete category. In set theory, morphisms are functions; in linear algebra, linear transformations; in group theory, group. g) These are pretty well known in the Haskell community. The integral monoid ring construction gives a functor from monoids to rings. See for example Ishikawa, Faithfully exact functors and their. instance Functor Maybe where fmap f Nothing = Nothing fmap f (Just x) = Just (f x) Maybe's instance of Functor applies a function to a value wrapped in a Just.

Monad. An exponential object XY is an internal hom [Y, X] in a cartesian closed category. 10:51. Pullback (category theory) In category theory, a branch of mathematics, a pullback (also called a fiber product, fibre product, fibered product or Cartesian square) is the limit of a diagram consisting of two morphisms f : X → Z and g : Y → Z with a common codomain. 6. Download : ometv. Indeed, we already saw in Remark 3. But many interesting Foldable s are also Functor s. Higher-Kinded Functor. e. A forgetful functor leaves the objects and the arrows as they are, except for the fact they are finally considered only as sets and maps, regardless of their. – user6445533. Coproduct. A constant functor is a functor whose object function is a constant function. If we want to make a type constructor an instance of Functor, it has to have a kind of * -> *, which means that it has to take exactly one concrete type as a type parameter. I'm preparing to deliver some lectures on homological algebra and category theory, and have found lots of nice long lists of examples of functors and categories arising in every-day mathematical practice. The next thing to notice is that the data itself any instance of the database is given by a set-valued functor I : C → Set. 2-functor. The motivating example is the (contravariant) functor that sends a graph to its set of vertex colorings with n colors. There's more to it, of course, so I'd like to share some motivation first. A functor is a promise. it looks like ,first apply function (a -> b) to the parameter of f a to create a result of type b, then apply f to it, and result is f b. In Haskell, the term functor is also used for a concept related to the meaning of functor in category theory. " Let F:C → D F: C → D be a functor. This functor has both left and right adjoints — the left adjoint is the left Kan extension along $ iota $ (regarded as a functor from $ H $ to $ G $ regarded as categories) and the right adjoint is the right Kan extension along $ iota $. It is a generalization of the map higher-order function. These are the induction functor $ operatorname{ind}_{H}^{G} $ which sends a $ H $-representation to the. So we have two cases: So we have two cases: [ pure x = (\_ -> x) ]: For pure we need to wrap a given -> r x into some functor but we are defining a function that just ignores input data type and returns data type x . 4. operator () (10); functoriality, (sr)m= s(rm):Thus a functor from this category, which we may as well write as R, to Ab is a left R-module. , every arrow is mapped to an arrow . Enriched functors are then maps between enriched categories which respect the enriched structure. Each object "knows" how to perform its tasks and interact with the other objects that constitute the application itself. A functor π:C → D is an op-fibration if, for each object x in C and each morphism g : π(x) → y in D, there is at least one π-coCartesian morphism f: x → y' in C such that π(f) = g. Tên của bạn Alamat email Isi. 6. Functor categories serve as the hom-categories in the strict 2-category Cat. 0 seconds of 5 minutes, 0Volume 90%. 4. You could add static variables to your function, but those would be used for any invocation of the function. Like monads, applicative functors are functors with extra laws and operations; in fact, Applicative is an intermediate class between Functor and Monad. Simontok– Nonton Video Bokep Indo Viral Funcrot Abg Mesum Di Gudang Sekolah terbaru durasi panjang full HD disini. But there is an equivalent definition that splits the multi-argument function along a different boundary. Then G is said to be right adjoint to F and F is said to be left adjoint to G if for all X ∈ Obj(C) and Y ∈ Obj(D) there. Such functors give representations of an abstract category in terms of known structures (i. Proof. In this case the nerve functor is the singular simplicial complex functor and the realization is ordinary geometric realization. We will encounter also the notion of a Green functor, which is a Mackey functor M with an extra multiplicative structure. Funcrot Website Dewasa Terlengkap, Nonton "Goyangan Nikmat Dari Pacar Mesum" Di Funcrot, Nonton Dan Baca Cerita Dewasa Hanya Di Funcrot. (Here [B, Set] means the category of functors from B to Set, sometimes denoted SetB . In fact. "Heheh keliatan yahh". 377-390. In Haskell this idea can be captured in a type class : classFunctorfwherefmap::(a->b)->fa->fb. Another interesting reason why categories cannot be identified always with categories having functions for morphisms is given in this paper, by Peter Freyd in which is proven that there are some categories which aren't concrete: i. It generalises the notion of function set, which is an exponential object in Set. Fold. 31:11 Bokep Jepang Konoha Threesome Crot Didalam. Bagi Bagi Record. The pullback is written. For example, we could define a functor for std::vector like this:A contravariant functor F: C → D is like a covariant functor, except that it "turns morphisms around" ("reverses all the arrows"). Suppose we are given a covariant left exact functor F : A → B between two abelian categories A and B. If C and D are M-categories (that is,. Functor. Free functor. ujarku. Functors were first considered in algebraic topology, where algebraic objects (such as. Anyways, this should hold in particular when F is the identity functor, which if understand correctly would correspond to the aforesaid function having the type a -> G a. This functor is left adjoint to the functor that associates to a given ring its underlying multiplicative monoid. This functor is representable by any one element set. Informally, I want to say that C "really is" a functor (although of course this is kind of an abuse of terminology. With the identity functor de ned we can de ne a new category De nition 3. 8. A functor is a morphism between categories. The function t-> if t < 2. Instances of std::function can store, copy, and invoke any CopyConstructible Callable target-- functions (via pointers thereto), lambda expressions, bind expressions, or other function objects, as well as pointers to member functions and pointers to data members. Category:. something that syntactically behaves as a function. In mathematics, a quotient category is a category obtained from another category by identifying sets of morphisms. , Either), only the last type parameter can be modified with fmap (e. Such left adjoints to a precomposition are known as left Kan extensions. Related concepts From Wikipedia, the free encyclopedia. A type f is a Functor if it provides a function fmap which, given any types a and b , lets you apply any function of type (a -> b) to turn an f a into an f b, preserving the structure of f. This is an artifact of the way in which one must compose the morphisms. We say that Xis the representing object of F. Higher-Kinded Functor. [2] Explicitly, if C and D are 2-categories then a 2-functor consists of. I'd go with tikz-cd and a key value interface: documentclass{article} usepackage{xparse,tikz-cd} ExplSyntaxOn NewDocumentCommand{functor}{O{}m} { group_begin. By results proved earlier Exti. Experts point out that a functor is created by overloading the operator and passing one argument the way that one would to a conventional function, albeit with different results. See also Category, Contravariant Functor, Covariant Functor, Eilenberg-Steenrod Axioms, Forgetful Functor, Morphism, Schur Functor, Tensor Product FunctorWe would like to show you a description here but the site won’t allow us. It has a GetAwaiter () method (instance method or extension method); Its. Up until now, we’ve seen OCaml’s modules play an important but limited role. The free functor you're referring to is an attempt to express the left adjoint of this functor just as for other "free-forgetful pairs". 2. A Functor is something that is Mappable or something that can be mapped between objects in a Category. Hence by the fully faithfulness of the Yoneda embedding, there is an. x stackrel {f} { o} y,. Apr 27, 2015 at 1:17 $egingroup$ @ZhenLin Of course it is the same, the goal is to retrieve the usual notion of adjunction, not a new one. 01:02:26 Indo Keseringan Diewe Titit Sampai Kendor. Functors are objects that behave as functions. More specifically, every morphism f : x → y in C must be assigned to a morphism F(f) : F(y) → F(x) in D. The typical diagram of the definition of a universal morphism. 0 from 0 to. e. For example, lists are functors over some type. Okay, that is a mouth full. JUL-756 Orang Yang Membuliku Meniduri Ibuku - Asahi Mizuno. The commutative diagram used in the proof of the five lemma. Functor is a type class that abstracts over type constructors that can be map‘ed over. A functor L: C → D L colon C o D is left adjoint to a functor R: D → C R colon D o C if and only if there is an isomorphism (not equivalence) of comma categories L ↓ D ≅ C ↓ R L downarrow D cong C downarrow R and this isomorphism commutes with the forgetful functors to the product category C × D C imes D. ; The print_it functor for for_each() we used in the previous section is a unary function because it is applied to. 01:44. fmap. Expand • Let M n( ) : CRing !Monoid be the functor sending a commutative ring to the monoid of matrices over that ring. Ab Ab -enriched categories with finite. a special function that converts a function from containees to a function converting containers. It is a minimal function which maps an algebra to another algebra. Repeating this process in Grp G r p. e. Example Maybe. a function may be applied to the values held within the structure/container without changing the (uh!) structure of the structure/container. A foldable container is a container with the added property that its items can be 'folded'. A functor M Set is just a set with a left A-action. In category theory, a Functor F is a transformation between two categories A and B. In the same way that we have Enumerable (Enum) in Elixir, you can also think of Functor as Functor-able, or, in more human language, Mappable. f^*E \to X. Indo Viral Funcrot Site Abg Mainin Toket Gede Bikin Sange . For definiteness take the set 1 = {0}. Sang mudir ini sangat disegani, begitu pula istrinya Nyi Laila. Nonton video dewasa dan baca cerita dewasa terbaru hanya di FunCrotFunction words belong to the closed class of words in grammar because it is very uncommon to have new function words created in the course of speech. Hence, a natural transformation can be considered to be a "morphism of functors". FUNCTOR definition: (in grammar ) a function word or form word | Meaning, pronunciation, translations and examplesComputational process of applying an Applicative functor. Functors used in this manner are analogous to the original mathematical meaning of functor in category theory, or to the use of generic programming in C++, Java or Ada.

A formal proof in cubical Agda is given in 1Lab. That type constructor is what the Functor instance is associated with, and gives the mapping for objects; the mapping for morphisms is fmap, which. Initial and terminal objects. Definition. Istriku pulang setelah Dzuhur, akupun memberikan air minum yang sudah diteteskan obat perangsang. Now let’s see what a functor is. 96580 views 100%. 85795 views 100%. Category theory has come to occupy a central position in contemporary mathematics and theoretical computer science, and is also applied to mathematical physics. When we write down the definition of Functor we carefully state two laws: fmap f . Functors. "Kamu jangan ajak Anisa ke tempat seperti ini yah ren". gửi email cho tác giả. Sketch of proof. A compound term is a structured type of data that starts with an atom known as a functor. The notion appears in representation theory as well. One issue is that the functor between Kleisli categories induced by a monad morphism goes in the direction opposite. #include <iostream> #include <algorithm> #include. To understand Functor, then,.

Representable functor. Define F:Ab → Ab F: A b → A b by letting F(G) =Z F ( G) = Z for every abelian group G G and F(f) =idZ F ( f. fmap is used to apply a function of type (a -> b) to a value of type f a, where f is a functor, to produce a value of type f b. However, Haskell being a functional language, Haskellers are only interested in functors where both the object and arrow mappings can be defined. g. The functor F is said to be. 02:16. So, you can think about a functor as a "function" (which indeed is not) between both objects and morphisms. So one could say a functor is composed of two "parts", one that maps Objects to Objects, and one that maps Morphisms to Morphisms. Applicative functors allow for functorial computations to be sequenced (unlike plain functors), but don't allow using results from prior computations in the definition. An enriched adjoint functor theorem is given in: 74 (1995) pp. mathcal {B}G is precisely a representing object for this functor; the universal element is the (isomorphism class of the) classifying [pi: mathcal.

Naperian functors are closed under constant unit (Phantom), product, exponentiation (a ->) aka Reader, identity. A type f is a Functor if it provides a function fmap which, given any types a and b , lets you apply any function of type (a -> b) to turn an f a into an f b, preserving the structure of f. In functional programming, fold (or reduce) is a family of higher order functions that process a data structure in some order and build a return value. The functor G G is called an anainverse of F F (so F F is an anainverse of G G). 4. Created with Blender and Gifcurry. Indo Viral Funcrot Site Abg Mainin Toket Gede Bikin Sange. such that each. A post in Functional JavaScript Blog states that a functor is a function that, “given a value and a function, unwraps the values to get to its inner value (s), calls the given function with the. For Haskell, a functor is a structure/container that can be mapped over, i. Add a comment. You can look at such a function as a mapping of a product (a pair, in Haskell) to another type (here, c ). Aku pun melihat sekitar rupanya banyak yang memperhatikanku. map (f) (please excuse my abuse of notation). Nonton Bokep Indo Bokep Cewe Indo Cantik Colmek Sampe CrotSo if it is possible, I would guess that it likely requires not just having "category" and "functor" as primitive notions, but also "$mathbf{1}$" and $"mathbf{2}"$ as primitive notions. Quotient category. It is basically an abstraction that allows us to write generic code that can be used for Futures, Options, Lists, Either, or any other mappable type. 00:00. g. A functor is a special case of a functionoid: it is a functionoid whose method is the “function-call operator,” operator()(). map, which takes a function on array elements and produces a function on arrays. Retracts are clearly preserved by any functor. Function declaration consists of the function name and its argument list along with its output. This means that it's both a "function" that takes a set and gives you back a set, and also a "function" that takes a morphism of sets (a function) and gives you back a morphism of sets. In category theory, monoidal functors are functors between monoidal categories which preserve the monoidal structure. but when (->) is used as a Functor (in Control. Data. 12. Then C C is equivalent (in fact, isomorphic) to the category of pairs (x, y) ∈ C ×D ( x, y) ∈ C × D such that F(x) = y F ( x) = y, where morphisms are pairs (f, F(f)): (x, y) → (x′,y′) ( f, F ( f)): ( x, y) → ( x ′, y ′). 21. Composable. 105114 views 100%. JavaScript’s built in array and promise. Instances (fmap show Just) 1 result is : "Just 1". You cannot do this with functors. A fuzzy explanation would be that a Functor is some sort of container and an associated function fmap that allows you to alter whatever is contained, given a function that transforms the contained. For any category E, a functor I o E is precisely a choice of morphism in E. But the book says that it is not satisfactory to call the set Hom X ( Z, X), the set of. Note that fixing the first argument of Hom naturally gives rise to a covariant functor and fixing the second argument naturally gives a contravariant functor. The following diagram depicts how an Applicative Functor acts as an endofunctor in the Hask category. Since Cat here is cartesian closed, one often uses the exponential notation C^B := [B,C] for the functor category. From monoids and groups to rings. HD 0 View 00:00:12. Chapter 1. function object implementing x - y. For instance, lists are this kind of container, such that fmap (+1) [1,2,3,4] yields [2,3,4,5]. Indo Funcrot Site Skandal Kating Ngewe Dengan Maba. Here is a proof that every functor is "forgetful. One example where the two uses of "map" coexist. A functor takes a pure function (and a functorial value) whereas a monad takes a Kleisli arrow, i. There are two ways to look at this. The case for locally presentable categories is discussed in. HD. Creating a Functor With this in. Funcrot Website Dewasa Terlengkap, Nonton "Ngintip Abg Di Kamar Mandi. Theorem 5. A functor is called contravariant if it reverses the directions of arrows, i. Now, say, type A and B are both monoids; A functor between them is just a homomorphic function f. Maybe can also be made a functor, such that fmap toUpper. Def: A contravariant functor between categories C C and D D contains the same data as a functor F: C → D F: C → D, except. Atau lihat video bokep skandal terbaru yang lagi rame di indonesia di Bokep Viral nonton berbagai. Functor. $egingroup$ I'm afraid the only references I can give you will just explain the construction and the properties of the six functors. , Either), only the last type parameter can be modified with fmap (e. Then there's an induced functor F ∗: [B, Set] → [A, Set] defined by composition with F. By definition, these are functors F: C → D F: C → D whose action on morphisms is an abelian group homomorphism C(A, B) → D(FA, FB) C ( A, B) → D ( F A, F B). In category theory, a branch of mathematics, an initial object of a category C is an object I in C such that for every object X in C, there exists precisely one morphism I → X . 08:21 Gadis Mulus Kena Crot 2 Kali. 1. In category theory, a faithful functor is a functor that is injective on hom-sets, and a full functor is surjective on hom-sets. From a syntactic perspective a functor is a container with the following API: import java. In programming languages like Scala, we can find a lot of uses for Functors. When covering the vital Functor and Monad type classes, we glossed over a third type class: Applicative, the class for applicative functors. fmap g = fmap (f . myFunctorClass functor; functor ( 1, 2, 3 ); This code works because C++ allows you to overload operator (), the "function call" operator. Yet more generally, an exponential. A lambda expression creates an nameless functor, it's syntactic sugar. Functors exist in both covariant and contravariant types.

Functor is exported by the Prelude, so no special imports are needed to use it. C++ Lambda Function Object or Functor. That new module is evaluated as always, in order of definition from top to bottom, with the definitions of M available for use. object. Some advantages of applicative functors. What's a typeclass? One of Haskell's selling points is its strong type system. In the context of enriched category theory the functor category is generalized to the enriched functor category. To implement a Functor instance for a data type, you need to provide a type-specific implementation of fmap – the function we already covered. Functor. If C C and D D are additive categories (i. You can define this functor for every four categories and two functors between them. Meaning of functor. A category is a quiver (a directed graph with multiple edges) with a rule saying how to compose two edges that fit together to get. ** The word "function" is in quotation marks in that sentence only because it's a kind of function that's not interchangeable with the rest of the functions we've already seen. Functions play a major role in Haskell, as it is a functional programming language. So the identity morphism is a morphism from some object to itself, and the identity functor is a functor which returns the object and morphism that it eats. 6. Each object "knows" how to perform its tasks and interact with the other objects that constitute the application itself. This entry contributed by Margherita Barile. Nonton dan. $endgroup$ – Zhen Lin. In mathematics, the inverse limit (also called the projective limit) is a construction that allows one to "glue together" several related objects, the precise gluing process being specified by morphisms between the objects. Suppose that if Fi is a -functor such that for any i>0 Fi is e↵acable. 00:20:56. The functor F induces a function. Then Fi = RiF0. When one has abelian categories, one is usually interested in additive functors. This is the ideal situation where functors can help. The traditional definition of an applicative functor in Haskell is based on the idea of mapping functions of multiple arguments. It enables a generic type to apply a function inside of it without affecting the structure of the generic type. For instance, there is a functor Set Gp that forms the free group on each set, and a functor F : Gp Ab that sends each group to its largest abelian quotient: F(X) is Xab = X/[X,X], the abelianization of X. Hence you can chain two monads and the second monad can depend on the result of the previous one. Simontok– Nonton Video Bokep Goyang Di Colmek Muncrat Daster 13 terbaru durasi panjang full HD disini. A functor F : C → Set is known as a set-valued functor on C. They are class objects which can overload the function operator. Functor Type Syntax and Semantics# The simplest syntax for functor types is actually the same as for functions:In mathematics higher-order functions are also termed operators or functionals. My hope is that this post will provide the reader with some intuition and a rich source of examples for more sophisticated category. Ukhti Masih SMA Pamer Tubuh Indah. Indo Viral Funcrot Site Abg Mainin Toket Gede Bikin Sange . Server. A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair. 3 of Grothendieck. 00:00. The definition also includes classes, since an object reference to a class is a callable that, when called, returns an object of the given class—for example, x = int(5). Ia memerintahkan agar Roy. Functors were first considered in algebraic topology, where algebraic objects (such as the fundamental group) are associated to topological spaces, and maps between these algebraic objects are associated to continuous maps between spaces. Monoid is based on an associative function. The ZipList is an applicative functor on lists, where liftA2 is implemented by zipWith. "Minimality" is expressed by the functor laws. In the absence of the axiom of choice (including many internal situations), the appropriate notion to use is often instead the anafunctor category. A naturalIn category theory, a branch of mathematics, a natural transformation provides a way of transforming one functor into another while respecting the internal structure (i. Miss V Prank Ojol 156 3 Mb) — Jilbabviral Com. Explaining how the Functor instance for functions shown above satisfies these laws is a great exercise in mind-bending Haskell notation, and really stresses our grasp of types and type constructors. This new functor has exactly the same structure (or shape) as the input functors; all that has changed is that each element has been modified by the input function. What is less well known is that the second actually follows from the first and parametricity, so you only need to sit down and prove one Functor law when you go. Category theory is a toolset for describing the general abstract structures in mathematics. Ia Melihat Royhan yg berjalan ke gedung Ri'ayah berdasarkan perintah kyainya tadi. For your another confusion, in axiomatic set theory, the sets are the most elementary things, and the functions are indeeded defined based on sets. Functor is not necessarily an object of some class with overloaded operator (). Functor is a related term of function.

A category consists of a collection of things and binary relationships (or transitions) between them, such that these relationships can be combined and include the “identity” relationship “is the same as. Representable s are containter-like functors that have a "special relationship" with another type that serves as an index into the Representable. The line, MyFunctor (10); Is same as MyFunctor. There is also a local definition of “the Kan extension of a given functor F F along p p ” which can exist even if the entire functor defined above does not. Using the formula for left Kan extensions in Wikipedia, we would. 1:58:47. Home Indo Indo Hijab Indo Live Full Pack Jav Sub Jav Uncensored Cerita. In mathematics, specifically, in category theory, a 2-functor is a morphism between 2-categories. map (function) (promise) = fmap (function) (promise) promise <- async (return 11) wait (map (sub2) (promise)) -- 9. In functional programming, a functor is a design pattern inspired by the definition from category theory that allows one to apply a function to values inside a generic type without changing the structure of the generic type. For one, the functor can contain internal state; a state that is valid for this invocation of the function object only. Here, f is a parametrized data type; in the signature of fmap, f takes a as a type.

For C++, a functor is simply a class supporting operator (); what one might refer to as a callable in Python. axiomatization of a sheaf theory with the six functor formalism introduced in [Kha2]. A (covariant) functor F with domain a locally small category C is said to be representable if it is naturally isomorphic to the hom functor HomC(x, −): C → Set for some object x in C. 6K Followers, 1. 00:07:44. 5. comonadic functor, monadicity theorem. const, but this may be overridden with a more efficient version.
