期刊介绍： All articles submitted to this journal are peer-reviewed. The AMS has a single blind peer-review process in which the reviewers know who the authors of the manuscript are, but the authors do not have access to the information on who the peer reviewers are. This electronic-only journal is devoted to research in representation theory and seeks to maintain a high standard for exposition as well as for mathematical content. Representation Theory is an open access journal freely available to all readers and with no publishing fees for authors.
