设R 是交换环, C 是一个半对偶R-模, X 是一个R-模类. 引入了X-GC-投射复形的概念,
证明了复形M 是XG C-投射的当且仅当M 的每个层次上的模都是XG C-投射模, 并且对任意的CX …

Let U be a (B, A)-bimodule, A and B be rings, and be a formal triangular matrix ring. In this
paper, we characterize the structure of relative Ding projective modules over T under some …

This is a study of Ding projective modules relative to a semidualizing module and related
topics. Firstly, we study DC-projective dimensions and DC-projective modules under change …

Abstract Let 𝒱, 𝒲, 𝒴, 𝒳 be four classes of modules. We introduce a notion of (𝒱, 𝒲, 𝒴, 𝒳)-
Gorenstein modules which unifies a number of well-known Gorenstein modules. Under …

This paper is a study of strongly Ding projective modules with respect to a semidualizing
module. The class of strongly Ding flat modules with respect to a semidualizing module is …

Let R be a commutative ring and C a semidualizing R-module. In this article, we introduce
and investigate the notion of DC-projective complexes. We first prove that a complex X is DC …
