Aims of the study of the discipline

To acquaint students with the basic concepts and methods of group theory and field theory, to study a number of important classes of groups and fields, as well as the most important classical results on groups and fields, to instill in students the ability to independently study educational and scientific literature in the field of mathematics, to expain some non-trivial constructions and techniques , used by working specialists.

As a result of studying the discipline the student should be able to:

– use the Sylow theorems to describe the structure of finite groups;

– decompose a finitely generated Abelian group into a direct product of primitive cyclic subgroups;

– calculate the lower and upper Central series of the group;

– build finite fields of a given order and perform calculations in them;

– build simple extensions of a given field and perform calculations in them;

– use the main theoretical results for solving computational problems related to groups, rings and fields.
