Course objectives
The course presents one of fundamental topics of modern algebra. It naturally follows the well-known theory of vector spaces and shows what happens if scalars form a ring and not a field. It presents the emerging concepts of projective, flat and injective modules and their structure properties. Doing it, there are used basic constructions like products, direct sums, kernels, cokernels and tensor products. The course prepares students to the use of modules 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 sequaences: short exact sequences, group Ext 6. Injective modules: injective modules, injective hull
