Prerequisites
Algebra I, Algebra II
Course Enrolment Limitations
The course is offered to students of any study field.
Course objectives
The goal is to continue the bachelor's course of algebra and acquaint students with the choosen areas of modern algebra. In particular:
- to introduce the language of category theory and illustrate it on examples;
- to explain the concept of an universal algebra with the emphasis on terms and free algebras;
- to present the basics of the theory of mudules with the emphasize on free, projective, flat and injective modules.
Learning outcomes
After the course, students should be able:
- to think in the language of category theory;
- to apply the basic ideas of universal algebra, including terms and free algebras;
- to understand module theory as the generalization of linear algebra;
- to apply the acquired knowledge to other areas of mathematics.
Syllabus
  • 1. Categories: categories, functors, natural transformations, examples. 2. Universal algebras: universal algebras, subalgebras, products, factor algebras, terms, free algebras, Birkhoff's theorem. 3. Modules: modules, submodules, homomorphisms, factor modules, products, direct sums, kernels, cokernels. 4. Free and projective modules: free modules, projective modules, semisimple modules. 5. Tensor product: tensor product and its properties. 6. Flat modules: flat modules, directed colimits, Lazard's theorem, regular rings. 7. Injective modules: injective modules, injective hull.
