摘要
引进了qnil-半交换环的概念,推广了半交换环.证明了:二级三角矩阵环(SM0T)是qnil-半交换环当且仅当环S,T都是qnil-半交换环;环R上的幂级数环R[[x]]是qnil-半交换环当且仅当R是qnil-半交换环.
We extend semmicommutative rings and define a new one called qnil-semicommutative ring.It is proved that the triangular matrix ring of order two (SM0T) is qnil-semicommutative if and only if Sand Tare qnil-semicommutative;R[[x]],the power series ring of R,is qnil-semicommutative if and only if so is R.
