n-Strongly Gorenstein Projective, Injective and Flat modules
In this paper, we study the relation between m-strongly Gorenstein projective (resp. injective) modules and n-strongly Gorenstein projective (resp. injective) modules whenever m=n, and the homological behavior of n-strongly Gorenstein projective (resp. injective) modules. We introduce the notion of n
