Chains of semidualizing modules

Abstract

Let (R,m,k)(R, \mathfrak{m}, k) be a commutative Noetherian local ring. We study the suitable chains of semidualizing RR-modules. We prove that when RR is Artinian, the existence of a suitable chain of semidualizing modules of length n=max{i0  mi0}n=\mathrm{max}\,\{\,i\geqslant 0\ |\ \mathfrak{m}^{i}\neq 0\,\} implies that the the Poincareˊ\acute{\mathrm{e}} series of kk and the Bass series of RR have very specific forms. Also, in this case we show that the Bass numbers of RR are strictly increasing. This gives an insight into the question of Huneke about the Bass numbers of RR.
