矩阵环的幂级数弱McCoy子环

Power-serieswise Weak Mc Coy Subrings of Matrix Rings

给出矩阵环的两个幂级数McCoy子环和两个幂级数弱McCoy子环,得到了幂级数弱McCoy环不是reduced环.

Two power-serieswise McCoy subrings and two power-serieswise weak McCoy subrings of matrix rings are identified in the present article.Power-serieswise weak McCoy ring is not reduced ring.
