Introduction to algebraic number theory

This course (36 hours) is a relatively elementary course which requires minimal prerequisites from commutative algebra for its understanding. Its first part (modules over principal ideal domains, Noetherian modules) follows to a certain extent the book of P. Samuel "Algebraic Theory of Numbers". Then integrality over rings, algebraic extensions of fields, field isomorphisms, norms and traces are discussed in the second part. In the main third part Dedekind rings, factorization in Dedekind rings, norms of ideals, splitting of prime ideals in field extensions, finiteness of the ideal class group and Dirichlet's theorem on units are treated.

Homological algebra

This course (25 hours) presents categories, functors, chain complexes, homologies, free, projective and injective objects in the category of modules over a ring, projective and injective resolutions, derived functors, Tor and Ext, cohomologies of modules over a finite group, restriction and corestriction.

Lectures on complete discrete valuation fields

This is a very short introduction to local fields and local class field theory. This course (36 hours) presents basic features of local fields and the local reciprocity map.
