Description

This lecture introduces the concept of functors in category theory, providing definitions, examples, and applications. It covers the composition of functors, associativity, identity functors, and forgotten functors that 'forget' about the structure on objects and morphisms. The lecture also discusses how functors preserve composition and identities, illustrating with examples from group theory. The presentation concludes by hinting at the next topic of natural transformations.
