On separable noncyclic extensions of rings
Published online by Cambridge University Press: 09 April 2009
Abstract
The separable cyclic extension of rings is generalized to a separable noncyclic extension of rings: a crossed product with a factor set over a ring (not necessarily commutative). A representation of separable idempotents for a separable crossed product is obtained, and simplifications for some special factor sets are also given.
