Category theory is at its best, I think, when it reflects what mathematicians actually do and shows how to do it better, when it functions as the mathematics of mathematics. It doesn’t contradict this, though, that category theory has its own internal structure, concepts, and aesthetics.

Category theory is really about building bridges between different areas of mathematics. 1.1 Deﬁnitions and examples This is just about setting up the terminology. There will be no theorems in this chapter. Deﬁnition 1.1. A category C consists of

The technical advance is that category theory provides a framework in which to organize formal systems and by which to translate between them, allowing one to transfer knowledge from one field to another. But this same organizational framework also has many compelling examples outside of Higher category theory is a subfield of category theory that concerns the study of n-categories and ∞-categories. homological dimension The homological dimension of an abelian category with enough injectives is the least non-negativer integer n such that every object in the category admits an injective resolution of length at most n . The category J is thought of as an "index category". One should consider this in analogy with the concept of an indexed family of objects in set theory. The primary difference is that here we have morphisms as well.

Category theory has come to occupy a central position in contemporary mathematics and theoretical computer science, and is also applied to mathematical physics. Roughly, it is a general mathematical theory of structures and of systems of structures.

Category theory formalizes mathematical structure and its concepts in terms of a labeled directed graph called a category, whose nodes are called objects, and whose labelled directed edges are called arrows (or morphisms). A category has two basic properties: the ability to compose the arrows associatively, and the existence of an identity arrow for each object. The language of category theory has been used to formalize concepts of other high-level abstractions such as sets, rings
