What is an adjunction category theory?
In mathematics, specifically category theory, adjunction is a relationship that two functors may have. Two functors that stand in this relationship are known as adjoint functors, one being the left adjoint and the other the right adjoint.
What are the two main types of adjunction?
Since there are various different levels of strictness at which one works in 2-category theory, there are various different kinds of 2-adjunction, including: A strict 2-adjunction, involving strict 2-categories, strict 2-functors, strict 2-natural transformations, and on-the-nose triangle identities.

How do functors work?
A functor (or function object) is a C++ class that acts like a function. Functors are called using the same old function call syntax. To create a functor, we create a object that overloads the operator(). Thus, an object a is created that overloads the operator().
What does Hom mean in math?
Hom(M,N) refers to the set of A-module homomorphisms from M to N. These form an abelian group under pointwise addition (define f+g by (f+g)(x)=f(x)+g(x)), and if A is commutative they in fact form an A-module by pointwise scalar multiplication (define a⋅f by (af)(x)=a⋅f(x)).

Which is the unit of an adjoint pair?
The unit of this adjoint pair is the defining pair of inclusion maps from X1 and X2 into the direct sum, and the counit is the additive map from the direct sum of ( X, X) to back to X (sending an element ( a, b) of the direct sum to the element a + b of X ).
