This volume, dedicated to Bruno J. Muller, a renowned algebraist, is a collection of papers that provide a snapshot of the diversity of themes and applications that interest algebraists today.

The papers highlight the latest progress in ring and module research and present work done on the frontiers of the topics discussed.

In addition, selected expository articles are included to give algebraists and other mathematicians, including graduate students, an accessible introduction to areas that may be outside their own expertise.
