ABSTRACT
Let S and R be rings and SCR be a semidualizing bimodule. We first give the definitions of C-transpose and n-C-torsionfree and give a criterion for a module A to be GC-projective by some property of the C-transpose of A. Then we introduce the notion of C-Gorenstein transpose of a module over two-sided Noetherian rings. We prove that a module M in mod Rop is a C-Gorenstein transpose of a module A ∈ mod S if and only if M can be embedded into a C -transpose of A with the cokernel GC-projective. Finally we investigate some homological properties of the C-Gorenstein transpose of a given module.

    In this paper we are concerned with the stability of the class of Gorenstein n-flat modules. We give an answer for the following natural question in the setting of a left GFn-closed ring R: Given an exact sequence of Gorenstein n-flat R-modules G = ... → G1 → G0 → G0...

    The question is addressed of when all pure-projective modules are direct sums of finitely presented modules. It is proved that this is the case over hereditary noetherian rings. Partial results are obtained for uniserial rings. Some of the methods are model-theoretic, and the techniques...

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...
