摘要
在k-闭*-半环的基础上,引入了指数稳定*-半环的概念,研究了它的性质,矩阵半环以及系数在其中的形式幂级数半环.得到指数稳定半环的矩阵半环不是指数稳定半环,证明了系数在指数稳定半环中的形式幂级数半环是指数稳定半环.
In this paper, we firstly introduce the concept of stable index star simmering on the base of k - closed star simmering. Then we study its property, matrix simmering and the simmering of formal power series with coefficients. The result is found that the matrix simmering of stable index simmering is not the stable index simmering. The result is proved that tile simmering of formal power series with coefficients is a stable index simmering.
