Structure Theorems Of Unit Groups (de Gruyter Textbook) [Hardcover]

This two-volume graduate textbook gives a comprehensive, state-of-the-art account of describing large subgroups of the unit group of the integral group ring of a finite group and, more generally, of the unit group of an order in a finite dimensional semi simple rational algebra. Supporting problems illustrate the results and complete some of the proofs. Volume 2 mainly is about structure theorems and geometric methods.
