Uniform Equivalence of Symbolic and Adic Topologies

Let (R,m) be a local ring. We study the question of when there exists a positive integer h such that for all prime ideals P ⊆ R, the symbolic power P (hn) is contained in P, for all n ≥ 1. We show that such an h exists when R is a reduced isolated singularity such that R either contains a field of positive characteristic and R is F -finite or R is essentially of finite type over a field of char...

On Toric Face Rings

Following a construction of Stanley we consider toric face rings associated to rational pointed fans. This class of rings is a common generalization of the concepts of Stanley–Reisner and affine monoid algebras. The main goal of this article is to unify parts of the theories of Stanley–Reisnerand affine monoid algebras. We consider (nonpure) shellable fan’s and the Cohen–Macaulay property. More...

Uniform topologies on types

We study the robustness of interim correlated rationalizability to perturbations of higher-order beliefs. We introduce a new metric topology on the universal type space, called uniform-weak topology, under which two types are close if they have similar first-order beliefs, attach similar probabilities to other players having similar first-order beliefs, and so on, where the degree of similarity...

Rationality for Generic Toric Rings

We study generic toric rings. We prove that they are Golod rings, so the Poincaré series of the residue field is rational. We classify when such a ring is Koszul, and compute its rate. Also resolutions related to the initial ideal of the toric ideal with respect to reverse lexicographic order are described.
