Cohomology Rings of Toric Wonderful Model

Algebraic Topology 2024-10-07 v1 Algebraic Geometry Combinatorics

Abstract

We describe the cohomology ring of toric wonderful models for arbitrary building set, including the case of non well-connected ones. Our techniques are based on blowups of posets, on Gr\"obner basis over rings and admissible functions.
