Module aim (aims)

Galois Cohomology is a one of the most important tools in Arithmetic Algebraic Geometry. The purpose of this course is a presentation of basic methods and results of Galois Cohomology. This course will also discuss results from other areas of Mathematics that are in the foundations of Galois Cohomology.

Pre-requisites in terms of knowledge, skills and social competences (where relevant)

Basic courses in Linear Algebra and  Abstract Algebra.
