摘要: 设R是有单位元的交换环, (L,A)是完备的对偶对. 先引入一种相对于完备对偶对(L,A)的Gorenstein同调模类GP(2)L, 再研究GP(2)L的一些性质. 最后, 借助一些特殊的模类证明GP(2)L与Gorenstein(L,A)-投射模类一致.

关键词: Gorenstein(L,A)-投射模, 稳定性, Gorenstein平坦模, 正合序列, 对偶对

Abstract: Let R be an associative ring with an identity, and (L,A) be a complete duality pair. Firstly, we introduce the class GP(2)L of Gorenstein homological modules with respect to the complete duality pair (L,A). Secondly,  we study some properties of GP(2)L. Finally, we prove that GP(2)L coincides with the class of Gorenstein (L,A)-projective modules with the help of some special classes of modules.

Key words: Gorenstein , (L,A)-projective module, stability, Gorenstein flat module, exact sequence, duality pair
