摘要
引入了幂级数弱McCoy环的概念。证明了:(1)设{Ri|i∈I}是一族环,如果每一个Ri(i∈I)是幂级数弱McCoy环,则∏i∈I Ri是幂级数弱McCoy环;(2)如果环R是一个诣零半交换环,则R[x]是幂级数弱McCoy环当且仅当R是幂级数弱McCoy环;(3)设环R是一个α-相容的诣零半交换环,则R[x;α]是幂级数弱McCoy环。
The concept of a power series weak Mc Coy ring is introduced. It is shown that( 1) if every Ri( i∈I) is a power series weak Mc Coy ring,then ∏i∈I Riis a power series weak Mc Coy ring;( 2) If R is a nil-semicommutative ring,then R[x] is a power series weak Mc Coy ring if and only if R is a power series weak Mc Coy ring;( 3) If R is aα-compatible nil-semicommutative ring,then R[x; α] is a power series weak Mc Coy ring.
