A sub-functor for Ext and Cohen-Macaulay associated graded modules with bounded multiplicity-II
Abstract
Let be a \CM\ local ring, then notion of -split sequence was introduced in part-1 of this paper for -adic filtration with the help of numerical function . We have explored the relation between AR-sequences and -split sequences. For a Gorenstein ring we define a Hom-finite Krull-Remak-Schmidt category as a quotient of the stable category . This category preserves isomorphism, i.e. in if and only if in .This article has two objectives; first objective is to extend the notion of -split sequence, and second objective is to explore function and -split sequence. When be an \anram\ \CM\ local ring and be an -primary ideal then we extend the techniques in part-1 of this paper to the integral closure filtration with respect to and prove a version of Brauer-Thrall-II for a class of such rings.
