Abstract:
This thesis generalize the idea of strongly Gorenstein projective(resp.injective,flat) modules
that is a particular case of Gorenstein projective (resp.injective,flat)modules,which,introduces
the notion of n-strongly Gorenstein projective(resp.injective,flat) modules for n ≥ 1 .
So we give some definition, properties, homological behaviour, characterization and a
relation between m-strongly Gorenstein projective(resp.injective,flat) module and n-strongly
Gorenstein prjective(resp.injective,flat) modules,where m and n are positive integers
