Course objectives
The course introduces categories and shows how they make possible a unified understanding of various concepts in other fields of mathematics and computer science. There are introduced functors and natural transformations, defined products, coproducts and general limits and colimits and there is shown what they mean in particular situations. Among others, there is explained a connection of cartesian closed categories with the typed lambda-calculus. The course culminates with the theory of adjoint functors and with their connection with such disparate topics like free algebras, tensor prducts and compactifications.
Syllabus
  • 1. Categories: definition, examples, constructions of categories, special objects and morphisms 2. Products and coproducts: definition, examples 3. Funtors: definition, examples, diagrams 4. Natural transformations: definition, examples, Yoneda lemma, representable functors 5. Cartesian closed categories: definition, examples, connections with the typed lambda-calculus 6. Limits: (co)equalizers, pullbacks, pushouts, limits, colimits, limits by products and equalizers 7. Adjoint functors: definition, examples, Freyd's theorem 8. Toposes: definition, examples
