Abstract  

We study the properties of McCoy rings with a doubly mapping, give some examples of this class rings, investigate their extensions and the *-nil McCoy property of *-skew polynomial rings. We showed that (1) Let *-ring R satisfy nil(R[x]) = nil(R)[x]. Then R is *-nil McCoy if and only if R[x] is *-nil McCoy; (2) Let R[x; *] be *-skew polynomial ring. If R is *-revisible, then R[x; *] is *-nil McCoy.

*-诣零McCoy环

研究了具有对合映射*-诣零McCoy环的性质,给出了一批*-诣零McCoy环例子,并讨论了其扩张和*-斜多项式环的*-诣零McCoy性,证明了(1)设*-环R满足nil(Rx])=nil(R)[x],则环R是*-诣零McCoy环当且仅当环Rx]是*-诣零McCoy环;(2)设Rx;*]是*-斜多项式环,如果R是*-可逆环,则Rx;*]是*-诣零McCoy环。
