Prerequisites
Algebra I, II, III
Course Enrolment Limitations
The course is offered to students of any study field.
Course objectives
The goal is to finish the course of algebra a use the acquired knowledge to the following topics:
- homological algebra
- finiteness conditions in the theory of modules
- commutative algebra in connections with algebraic geometry
- representations of groups.
Learning outcomes
After finishing the course, students will have an idea about special methods of algebra and their use. In particular they will be able:
- to use methods of homological algebra;
- to have an idea how finite dimensionality is extended from linear algebra to the theory of modules;
- to understand basic techniques of commutative algebra in connections with algebraic geometry;
- to appreciate the power of representations of groups by matrices.
Syllabus
  • 1. Chain complexes: chain complexes, exactness, homology, projective and injective resolutions. 2. Derived functors: derived functors, Functor Ext, functor Tor, extensions of modules, the connection with the group Ext. 3. Homological dimension: projective and injective dimension of a module, global dimension of a ring. 4. Noetherian rings and modules: noetherian modules, artinian modules, radical of a ring, Nakayama lemma. 5. Commutative algebra: Dedekind rings, local rings, localization, primary decomposition, spectrum of a ring, connections with algebraic geometry. 6. Linear representations of groups: group rings and group algebras and modules over them, irreducible representations, Schur lemma, Maschke theorem. 7. Characters of groups: characters, orthogonality, applications to finite groups, induced representations, Frobenious reciprocity theorem.
