Let A and B be rings, U a (B, A)-bimodule and T= A 0 UB be a triangular matrix ring. We first
give an explicit description for Gorenstein injective T-modules over the triangular matrix ring …

Let $ T $ be a right exact functor from an abelian category $\mathscr {B} $ into another
abelian category $\mathscr {A} $. Then there exists an abelian category, named comma …

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 …

Let A and B be rings and U a (B, A)-bimodule. If BU is flat and UA is finitely generated
projective (resp., BU is finitely generated projective and UA is flat), then the characterizations …

摘要 Let A and B be rings and U be a (B, A)-bimodule. If UB has finite flat dimension, UA has
finite flat dimension and U circle times (A) C is a cotorsion left B-module for any cotorsion left …

We introduce the dual notions of E (X, M, Y) and M (X, M, Y), and investigate when they have
enough injective objects or projective objects, when they are resolving or co-resolving, and …

Suppose that $ T=\left (\begin {smallmatrix} A&0\\U&B\end {smallmatrix}\right) $ is a formal
triangular matrix ring, where $ A $ and $ B $ are rings and $ U $ is a $(B, A) $-bimodule. Let …
