G-semisimple algebras
Rasool Hafezi, Abdolnaser Bahlekeh
Let be an Artin algebra and ${\mathsf{mod}}\mbox{-} ({\underline{\mathsf{Gprj}}}\mbox{-}Λ)$ the category of finitely presented functors over the stable category ${\underline{\m…
2-categorical approach to unifying constructions of precoverings and its applications
Rasool Hafezi, Hideto Asashiba, Mohammad Hossein Keshavarz
Throughout this paper is a fixed group, and is a fixed field. All categories are assumed to be -linear. First we give a systematic way to induce -precoverings by adjo…
Relative Higher Homology and Representation Theory
Rasool Hafezi, Javad Asadollahi, Yi Zhang
Higher homological algebra, basically done in the framework of an -cluster tilting subcategory of an abelian category , has been the topic of several…
Homotopy category of projective complexes and complexes of Gorenstein projective modules
Javad Asadollahi, Rasool Hafezi, Shokrollah Salarian
Let be a ring with identity and $\C(R)$ denote the category of complexes of -modules. In this paper we study the homotopy categories arising from projective (resp. injective…
