Description

This lecture covers the definition of categories, including directed graphs, subgraphs, and composition maps. It also explores examples of concrete categories like Set, Top, Gr, Ab, and Chk, and discusses the product of categories. The concept of opposite categories and isomorphisms are introduced, leading to the notion of groupoids.
