σ-斜拟McCoy环

σ-Skew Quasi McCoy Rings

引入σ-斜拟Mc Coy环的概念并研究了其基本性质,证明了环R是σ-斜拟Mc Coy环当且仅当环DUT_n(R)是σ-斜拟Mc Coy环,推广了σ-斜Mc Coy环和σ-斜拟Armendariz环的相应结果.

The notion of δ-skew quasi McCoy ring was introduced and some basic properties of such rings were stud- ied. It showed that a ring R is δ-skew quasi McCoy ring if and only if the ring DUT （R） is δ-skew quasi McCoy ring. This generalizes the corresponding results of δ-skew McCoy rings and δ-skew quasi Armendariz rings.
