摘要

Let R be a commutative Noetherian ring and I a proper ideal of R. In this paper, we study finitely generated R-modules M with only one non-vanishing local cohomology module \({H}_I^c(M)\) H I c ( M ) where \(c=cd(I,M)\) c = c d ( I , M ) . Let C be a semidualizing R-module. We investigate the conditions under which \({H}_I^c(M)\) H I c ( M ) belongs to either the Auslander class \(\mathscr{A}_C(R)\) A C ( R ) or the Bass class \(\mathscr{B}_C(R)\) B C ( R ) .
