Self-Dual Codes and Invariant Theory

From the reviews: "This book under review the general notions of form rings and their representations ... . This book, introducing a new unifying theory and its applications to a wealth of substantial examples, is certainly written for experts in the field." (Jurgen Muller, Mathematical Reviews, Issue 2007 d)
