In this paper, we show that the homotopy category of N-complexes of projective R-modules
is triangle equivalent to the homotopy category of projective TN− 1 (R)-modules where TN …

Let R be a ring with identity and C (R) denote the category of complexes of R-modules. In
this paper we study the homotopy categories arising from projective (resp. injective) …

A general principle suggests that" anything flat is a directed colimit of countably presentable
flats". In this paper, we consider resolutions and coresolutions of modules over a countably …

A module is said to be copure injective if it is injective with respect to all modules A⊂ B with
B/A injective. We first characterize submodules that have the extension property with respect …

Given a bimodule M over an exact category C, we define an exact category CM with a
projection to C. This construction classifies certain split square-zero extensions of exact …

Here a topological R-left module. Y is called topologically coherent if it admits a basis of
neighborhoods of 0 consisting of submodules X'such that-X/S'is coherent in the category of …

Krause studied the homotopy category K (Inj A) of complexes of injectives in a locally
noetherian Grothendieck abelian category A. Because A is assumed locally noetherian, we …
