Rings, Extensions, and Cohomology

ANDY R. MAGID is George Lynn Cross Research Professor of Mathematics at the University of Oklahoma, Norman. The coeditor of two volumes of conference proceedings and the author or coauthor of three books and over 60 research papers, Dr. Magid is a member of the Mathematical Association of America and an officer of the American Mathematical Society. His primary research interests are in abstract algebra, especially the theory of algebraic groups and discrete groups and the applications of the former in the study of the representation theory of the latter. He received the B.A. degree (1966) in mathematics from the University of California at Berkeley and the Ph.D. degree (1969) in mathematics from Northwestern University, Evanston, Illinois.
