The International Conference on Algebra and its Applications held in Athens, Ohio, June 18 21, 2008 and sponsored by the Ohio University Center for Ring TheoryanditsApplications(CRA)hadasitscentralpurposetohonorSurenderK. Jain, the Center s retiring ?rst director, on the dual occasion of his 70th birthday and of his retirement from Ohio University. With this volume we celebrate the contributions to Algebra of our distinguished colleague. One of Surender s main attributes has been the way in which he radiates enthusiasm about mathematical research; his eagerness to pursue mathematical problems is contagious; we hope that reading this excellent collection of scholarly writings will have a similar e?ect onourreadersandthatyouwillbeinspiredtocontinuethepursuitofRingTheory as well as Algebra and its Applications. As with previous installments of CRA conferences, the underlying principle behind the meeting was to bring together specialists on the various areas of - gebra in order to promote communication and cross pollination between them. In particular, a common philosophy of our conferences through the years has been to bringalgebraistswho focus onthe theoreticalaspects ofour?eld withthose others who embraceapplicationsofAlgebraindiverseareas.Clearly, asa re?ectionofthe interests of the organizers, the applications we emphasized were largely within the realmofCoding Theory.The philosophybehind the organizationofthe conference has undoubtedly impacted this Proceedings volume.

This volume consists of refereed research and expository articles by both plenary and other speakers at the International Conference on Algebra and Applications held at Ohio University in June 2008, to honor S.K. Jain on his 70th birthday. The articles are on a wide variety of areas in classical ring theory and module theory, such as rings satisfying polynomial identities, rings of quotients, group rings, homological algebra, injectivity and its generalizations, etc. Included are also applications of ring theory to problems in coding theory and in linear algebra.
