Proceedings of a conference held in Evanston, Illinois, in August 1993. Topics include contributions of PI theory to Azumaya algebras, cocycles and right crossed products, Engel-type theorems for Lie color algebras, galois extensions of very local number rings, smoothing coherent torsion-fee sheaves, projective covers and quasi-isomorphisms, dihedral algebras and conjugate splittings, separability and the Jones polynomial, bicomplexes and galois cohomology, adjoining idempotents.

"Presenting the proceedings of a conference held recently at Northwestern University, Evanston, Illinois, on the occasion of the retirement of noted mathematician Daniel Zelinsky, this novel reference provides up-to-date coverage of topics in commutative and noncommutative ring extensions, especially those involving issues of separability, Galois theory, and cohomology."
