This volume consists of contributions by speakers at a
Conference on Algebra and Its Applications that took place in Athens, Ohio, in
March of 2005. It provides a snapshot of the diversity of themes and
applications that interest algebraists today. The papers in this volume
include some of the latest results in the theory of modules, noncommutative
rings, representation theory, matrix theory, linear algebra over noncommutative
rings, cryptography, error-correcting codes over finite rings, and
projective-geometry codes, as well as expository articles that will provide
algebraists and other mathematicians, including graduate students, with an
accessible introduction to areas outside their own expertise.

The book will serve both the specialist looking for the latest result and
the novice seeking an accessible reference for some of the ideas and
results presented here.
