This book contains the doctoral dissertations of three students from Novosibirsk who participated in the seminar of L. A. Bokut'. The dissertation of Gerasimov focuses on Cohn's theory of noncommutative matrix localizations. Gerasimov presents a construction of matrix localization that is not directly related to (prime) matrix ideals of Cohn, but rather deals with localizations of arbitrary subsets of matrices over a ring. The work of Valitskas applies ideas and constructions of Gerasimov to embeddings of rings into radical rings (in the sense of Jacobson) to develop a theory essentially parallel to Cohn's theory of embeddings of rings into skew fields. Nesterenko's dissertation solves some important problems of Anan'in and Bergman about representations of (infinite-dimensional) algebras and categories in (triangular) matrices over commutative rings.
Designed to acquaint students of particle physics already familiar with SU(2) and SU(3) with techniques applicable to all simple Lie algebras, this text is especially suited to the study of grand unification theories.

A word u in the alphabet X is called a 2 - word if any letter XiE X that occurs in the notation of this word has exactly two entries in u . Formal linear combinations of 2 - words with coefficients from the ground field K are called 2 ...
A graduate course in non-commutative or homological algebra, which is standard in most universities, is a prerequisite for readers of this book.
This book is an expanded version of the lectures given at the Nankai Mathematical Summer School in 1997.
