The purpose of coding theory is the design of efficient systems for the transmission of information. The mathematical treatment leads to certain finite structures - the error-correcting codes. Surprisingly, problems which are interesting for the design of codes turn out to be closely related to problems studied partly earlier and independently in pure mathematics. This book is about an example of such a connection. It is about the relation between codes and lattices. Lattices are studied in number theory and in the geometry of numbers. Many problems about codes have their counterpart in problems about lattices and sphere packings. The book starts with the basic definitions and examples of lattices and codes. A central theme is a fundamental correspondence between binary linear codes and certain integral lattices. The theta function of a lattice is introduced and it is shown that it is a modular form. Several applications of the theory of modeular forms to weight enumerators of codes are discussed. The classification of even unimodular lattices up to dimension 24 is studied using theta functions with spherical coefficients. Special attention is devoted to the Leech lattice, its constructions and the sphere covering determined by it. Finally, the book contains a detailed account on recent results of G. van der Geer and F. Hirzebruch concerning a generalization of some of the relations studied earlier in the book to self-dual codes over certain finite fields with more than two elements and lattices over the integers of certain algebraic fields. The book can serve as a text for a course. It should also be of use for students and mathematicians working in number theory, geometry or coding theory.

From the reviews of the third edition:

“In the book under review, Ebeling explores the mathematical theory of lattices and the ways that it is used by coding theorists. ... I very much enjoyed reading Ebeling’s book. ... This book contains some exciting mathematics, and I would recommend it to a graduate student or faculty member looking to learn about the field.” (Darren Glass, MAA Reviews, April, 2013)

The purpose of coding theory is the design of efficient systems for

the transmission of information. The mathematical treatment leads to

certain finite structures: the error-correcting codes. Surprisingly

problems which are interesting for the design of codes turn out to be

closely related to problems studied partly earlier and independently

in pure mathematics. In this book, examples of such connections are

presented. The relation between lattices studied in number theory and geometry and error-correcting codes is discussed. The book provides at the same time an introduction to the theory of integral lattices and modular forms and to coding theory.

In the 3rd edition, again numerous corrections and improvements have been made and the text has been updated.

More basic material has been included to make the text even more self-contained. A new section on the automorphism group of the Leech lattice has been added. Some hints to new results have been incorporated. Finally, several new exercises have been added.
