摘要: 首先, 引入复形的Gorenstein AC平坦维数的定义, 并对任意复形M, 给出GFacdim M≤n的刻画; 其次, 证明若复形M有有限的Gorenstein AC平坦维数, 则M存在一个完全AC分解.

关键词: 复形, Gorenstein AC平坦模, 完全AC分解

Abstract: Firstly, we introduced the definition of Gorenstein AC flat dimension for complexes and gave some characterizations of GFacdim M≤n for any complex M. Secondly, we proved that if the complex M had finite Gorenstein AC flat dimension, then M had a complete AC resolution.

Key words: complex, Gorenstein AC flat module, complete AC resolution
