ABSTRACT
We study classes of relative injective and projective comodules and extend well-known results about projective comodules given in [7]. The existence of covers and envelopes by these classes of comodules is also studied and used to characterize the projective dimension of a coalgebra. We also compare this homological coalge bra with the very intensively studied homological algebra of the dual algebra (see [5]).

    In basic homological algebra, projective, injective and flat modules play an important and fundamental role. In this paper, we discuss some properties of Gorenstein projective, injective and flat modules and study some connections between Gorenstein injective and Gorenstein flat modules. We also...

    In general, the injective cover (projective envelope) of a simple module can be zero. A ring R is called a weakly left V-ring (strongly left Kasch ring) if every simple left R-module has a nonzero injective cover (projective envelope). It is proven that every nonzero left R-module has a nonzero...

    We show that over a right coherent left perfect ring R, a complex C of left R-modules is Gorenstein projective if and only if C is Gorenstein projective in R-Mod for all m ∈ ℤ. Basing on this we show that if R is a right coherent left perfect ring then Gpd( C) = sup{Gpd( C)| m ∈...

    In this paper, we introduce and study the rings of Gorenstein homological dimensions less than or equal to 1. We call these Gorenstein (semi)hereditary rings and call a particular subclass of these strongly Gorenstein (semi)hereditary rings.

    In this paper, we first study RD-projective and RD-injective modules using, among other things, covers and envelopes. Some new characterizations for them are obtained. Then we introduce the RD-projective and RD-injective dimensions for modules and rings. The relations between the RD-homological...
