Course objectives
The course introduces students to the theory of modules, one of fundamental topics of modern algebra.

At the end of the course students should be able to:
*explain basic notions (modules, homomorphisms, submodules, quotient modules, products, direct sums, tensor products);
*know the basics of the theory of projective, flat and injective modules and their structure properties;
*understand module theory as an extension of linear algebra and connections to universal algebra;
*apply module theory in geometry and topology.
  • Modules: modules, submodules, homomorphisms, quotient modules, products, direct sums, kernels, cokernels 2. Free and projective modules: free modules, projective modules, semisimple rings, vector spaces 3. Tensor product: tensor product and its properties 4. Flat modules: flat modules, directed colimits, Lazard's theorem, regular rings 5. Short exact sequences: short exact sequences, group Ext 6. Injective modules: injective modules, injective hull

Teaching methods
The course is offered two hours each week plus one hour of exercises. It initiates a discussion with students.
Assessment methods
Course ends by an oral exam. Presence at the course is recommended, at the exercises is obligatory. Homeworks are given but not controled.
