三角形矩阵环上模的Gorenstein同调维数

Gorenstein homological dimensions of modules over triangular matrix rings

Rongmin Zhu, Zhongkui Liu, Zhanping Wang

摘要:

设$A$和$B$是环,$U$是$(B, A)$ -双模,$T=\left(\begin{smallmatrix} A & 0 \\ U & B \\\end{smallmatrix}\right)$是三角形矩阵环.本文刻画了$T$上模的Gorenstein同调维数,并讨论了左$T$ -模何时是强Gorenstein投射模或强Gorenstein内射模.

英文摘要:

Let $A$ and $B$ be rings, $U$ a $(B, A)$-bimodule and $T=\left(\begin{smallmatrix} A & 0 \\ U & B \\\end{smallmatrix}\right)$ be the triangular matrix ring. In this paper, we characterize the Gorenstein homological dimensions of modules over $T$, and discuss when a left $T$-module is strongly Gorenstein projective or strongly Gorenstein injective module.
