Aims of the study of the discipline

To acquaint students with the basic concepts and methods of the theory of rings, to study a number of the most important classes of rings, and also the most important classical results about rings, t 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:

to express a symmetric polynomial elementary symmetric;

– perform actions in the factor ring;

– finding generators of ideals in and out .

– decompose the ring into a straight product of a prick;

– perform basic operations on ideals of rings;

– apply the most important theoretical results to the solution of computational problems related to rings



algebra and number theory
