摘要
In this article, we investigate the relations between Gorenstein projective modules and Gorenstein flat modules in terms of strict Mittag-Leffler condition. We give some conditions under which Gorenstein projectives are Gorenstein flat, and discuss when the direct limits of Gorenstein projective modules are Gorenstein flat. Moreover, we study the dual of Gorenstein injective modules with strict Mittag-Leffler condition.
