A tight closure approach to a result of G. Faltings

Tirdad Sharif

Using a result of M. Hochster and C. Huneke on -rational rings a criterion for complete intersection rings of characteristic is presented. As an application, we give a com…

AB-Contexts and Stability for Gorenstein Flat Modules with Respect to Semidualizing Modules

Sean Sather-Wagstaff, Tirdad Sharif, Diana White

We investigate the properties of categories of G_C-flat R-modules where C is a semidualizing module over a commutative noetherian ring R. We prove that the category of all G_C-flat…

Homological flat dimensions

Parviz Sahandi, Tirdad Sharif, Siamak Yassemi

For finitely generated module over a local ring , the conventional notions of complete intersection dimension $\cid_R M$ and Cohen-Macaulay dimension $\cmdim_R M$ do not ext…

Gorenstein cohomology in abelian categories

Sean Sather-Wagstaff, Tirdad Sharif, Diana White

We investigate relative cohomology functors on subcategories of abelian categories via Auslander-Buchweitz approximations and the resulting strict resolutions. We verify that certa…

Comparison of relative cohomology theories with respect to semidualizing modules

Sean Sather-Wagstaff, Tirdad Sharif, Diana White

We compare and contrast various relative cohomology theories that arise from resolutions involving semidualizing modules. We prove a general balance result for relative cohomology…

Special homological dimensions and Intersection Theorem

Tirdad Sharif, Siamak Yassemi

Let $(R,\fm)$ be commutative Noetherian local ring. It is shown that is Cohen--Macaulay ring if there exists a Cohen--Macaulay finite (i.e. finitely generated) --module with…
