On Gorenstein Projective, Injective and Flat Dimensions — a Functorial Description with Applications
Gorenstein homological dimensions are refinements of the classical homological dimensions, and finiteness singles out modules with amenable properties reflecting those of modules over Gorenstein rings. As opposed to their classical counterparts, these dimensions rarely come with practical and robust criteria for finiteness, even over commutative noetherian local rings. Indeed, over such a ring ...
هدف این پروژه نشان دادن این است که اگر r یک حلقه ی موضعی جابه جایی cohen-macaulary باشد که دارای یک مدول dualizing مانند ? است، آنگاه پوشش ?- گرنشتاین یکدست و ?- گرنشتاین پروژکتیو برای رده ی خاصی از مدولها وجود دارد. این نتایج، نتایج شناخته شده ی قبلی را که برای حلقه های گرنشتاین موضعی اثبات شده اند را به حلقه ی موضعی جابه جایی cohen-macaulary که دارای مدول dualizing می باشند، توسعه می دهد. به...
Let R be a right GF-closed ring with finite left and right Gorenstein global dimension. We prove that if I is an ideal of R such that R/I is a semi-simple ring, then the Gorensntein flat dimensnion of R/I as a right R-module and the Gorensntein injective dimensnnion of R/I as a left R-module are identical. In particular, we show that for a simple module S over a commutative Gorensntein ring R, ...
Given an additive equational category with a closed symmetric monoidal structure and a potential dualizing object, we find sufficient conditions that the category of topological objects over that category has a good notion of full subcategories of strong and weakly topologized objects and show that each is equivalent to the chu category of the original category with respect to the dualizing obj...
throughout this dissertation r is a commutative ring with identity and m is a unitary r-module. in this dissertation we investigate submodules of multiplication , prufer and dedekind modules. we also stat the equivalent conditions for which is ring , wher l is a submodule of afaithful multiplication prufer module. we introduce the concept of integrally closed modules and show that faithful mu...
We introduce and study a class of objects that encompasses Christensen Foxby’s semidualizing modules complexes Kubik’s quasi-dualizing modules: the [Formula: see text]-adic complexes. give examples equivalent characterizations these objects, including characterization in terms more familiar property. As an application, we proof existence dualizing over complete local rings does not use Cohen St...
