About this book

Let FG be the group ring of a group G over a field F. Write U(FG) for the group of units of FG. It is an important problem to determine the conditions under which U(FG) satisfies a group identity. In the mid 1990s, a conjecture of Hartley was verified, namely, if U(FG) satisfies a group identity, and G is torsion, then FG satisfies a polynomial identity. Necessary and sufficient conditions for U(FG) to satisfy a group identity soon followed.

Since the late 1990s, many papers have been devoted to the study of the symmetric units; that is, those units u satisfying u* = u, where * is the involution on FG defined by sending each element of G to its inverse. The conditions under which these symmetric units satisfy a group identity have now been determined.

This book presents these results for arbitrary group identities, as well as the conditions under which the unit group or the set of symmetric units satisfies several particular group identities of interest.

Reviews

From the reviews:

“This book is concerned with one of the main directions in the study of group rings, namely, questions around group identities satisfied by units … . This is a nicely written book, understanding of which requires familiarity with groups and rings on the level of introductory graduate courses. Its publication is timely, taking into account the progress made in the considered theme, and I believe that it is both interesting and useful for everyone with an eye to group rings.” (Michael Dokuchaev, Mathematical Reviews, Issue 2012 d)

“The author undertakes the laborious task of expounding the … structure of unit groups of group algebras and of units of group algebras symmetric to the classical involution … . The likely reader … may not only be the specialist but the scholar whose research interests have connections with either group or ring theory … . The extensive bibliography of items relating to topics discussed allows the curious reader to gain an even deeper insight to a specific question by consulting the literature.” (János Kurdics, Zentralblatt MATH, Vol. 1203, 2011)
