Providence
Combinatorics Seminar Presents Anastasia Nathanson (Minnesota)
Title: Multipermutohedral Chow ringsAbstract:The multipermutohedral Chow ring was introduced in a series of papers by Clader, Damiolini, Eur, Huang, Li, and Ramadas to study moduli spaces with cyclic symmetry. It is analogous to the Chow ring of a type A permutohedral variety and generalizes those of type B. In this talk, we establish the combinatorial structure of the multipermutohedral Chow ring through an explicit Gröbner basis and use that to derive a combinatorial formula for its Hilbert series, and realize the unimodality and palindromicity of the Hilbert sequence as equivariant maps.
