On the set of Chern numbers in local rings

Commutative Algebra 2022-06-13 v1

Abstract

This paper purposes to characterize Noetherian local rings (R,m)(R, \mathfrak{m}) such that the Chern numbers of certain m\mathfrak{m}-primary ideals in RR bounded above or range among only finitely many values. Consequently, we characterize the Gorensteinness, Cohen-Macaulayness, generalized Cohen-Macaulayness of local rings in terms of the behavior of its Chern numbers.
