三角形矩阵环的Auslander型条件

The Auslander-Type Condition of Triangular Matrix Rings

Chonghui Huang, Zhaoyong Huang

摘要:

设$R$是左、右Noether环,$n,k$是任意非负整数. $R$被称为满足Auslander型条件$G_n(k)$,如果$R_R$的最小内射分解中的$(i+1)$ -st项的右平坦维数对于任何$0 \leq i \leq n-1$至多是$i+k$。本文证明了$R$是$G_n(k)$当且仅当是$R$上任意次$t$的下三角形矩阵环.

英文摘要:

Let $R$ be a left and right Noetherian ring and $n,k$ any non-negative integers. $R$ is said to satisfy the Auslander-type condition $G_n(k)$ if the right flat dimension of the $(i+1)$-st term in a minimal injective resolution of $R_R$ is at most $i+k$ for any $0 \leq i \leq n-1$. In this paper, we prove that $R$ is $G_n(k)$ if and only if so is a lower triangular matrix ring of any degree $t$ over $R$.
