|
Abstract:
本文介绍了Gorenstein内射模的类GI上的严格的Mittag-Leffler模，并用余挠对证明了GI-投射模在Gorenstein内射模的类GI上的严格的Mittag-Leffler模的一些同调性质。
In this paper, the strict Mittag-Leffler module over the class GI of Gorenstein injective modules is introduced, and some homological properties of GI-projective module at the strict Mittag-Leffler module over the class GI are proved by cotorsion pair.
