摘要
利用Ext函子,Tor函子与具有有限Gorenstein平坦维数的模类给出了n-GF-内射模与n-GF-平坦模的定义,给出n-GF-内射模与n-GF-平坦模的一些性质及它们的关系,并利用它们及n-GF-投射模刻画半单环等.
By using the concept of Ext functor, Tor functor and the class of modules with finite Goren- stein flat dimension, the concepts of n-GF-injective modules and n-GF-flat modules are introduced; some properties and relationship of n-GF-injective modules and n-GF-flat modules are given, as appli- cations, semisimple rings are characterized by n-GF-projective modules.
