SKEW POLYNOMIAL RINGS OVER GENERALIZED GCD DOMAINS

摘要

A ring R is said to be a right generalized GCD domain if any finitely generated right v-ideal is a projective generator of the category Mod-iJ of right jR-modules. A skew polynomial ring D[x, cr] over a commutative generalized GCD domain D is a right generalized GCD domain, where a is an aoutomorphism with finite order.
