Homological Functors of Local Cohomology Modules

Описание:

Let 'a' be an ideal of a commutative Noetherian ring R and let 'X' be an arbitrary R-module. In this book, we discuss the properties of extension module Ext^s_R(N, H^t_a(X)) and torsion module Tor_R^s(N, H^t_a(X)) which present some results about cofiniteness, Bass numbers, Betti numbers and projective dimensions of local cohomology modules. Also, we study section functors of local cohomology modules which has some results about Artinian and non-Artinian local cohomology modules.
