摘要: 设T是形式三角矩阵环,其中A,B是环且U是(B,A)-双模,给出了形式三角矩阵环T上Gorenstein FP-内射左T-模的刻画,进而讨论了左T-模的Gorenstein FP-内射维数.

关键词: Gorenstein FP-内射左T-模, 左GFPI-封闭环, Gorenstein FP-内射维数

Abstract: Let T be a formal triangular matrix ring, where A and B are rings and U is a(B, A)-bimodule. A characterization of Gorenstein FP-injective left T-modules over the formal triangular matrix ring T is given. Moreover, the Gorenstein FP-injective dimension of a left T-module is discussed.

Key words: Gorenstein FP-injective left T-module, left GFPI-closed ring, Gorenstein FP-injective dimension
