Lecture

Equivalences of Categories

Description

This lecture starts by studying examples of existence and non-existence of natural transformations, then moves on to the concept of equivalence of categories, exploring concrete examples such as equivalences between categories of the form BG for G a group. Towards the end, the notion of adjunction is introduced, along with a first class of specific examples, where one of the categories involved is Un.
