Serre's Condition R_l for Affine Semigroup Rings
Marie A. Vitulli
In this note we characterize the affine semigroup rings K[S] over an arbitrary field K that satisfy condition R_l of Serre. Our characterization is in terms of the face lattice of…
Weak subintegral closure of ideals
Terence Gaffney, Marie A. Vitulli
We describe some basic facts about the weak subintegral closure of ideals in both the algebraic and complex-analytic settings. We focus on the analogy between results on the integr…
Some Results On Normal Homogeneous Ideals
Les Reid, Leslie G. Roberts, Marie A. Vitulli
In this article we investigate when a homogeneous ideal in a graded ring is normal, that is, when all positive powers of the ideal are integrally closed. We are particularly intere…
Some normal monomial ideals
Marie A. Vitulli
In this paper we investigate the question of normality for special monomial ideals in a polynomial ring over a field. We first include some expository sections that give the basics…
