Posets for Specht ideals of essential real reflection groups

Combinatorics 2025-06-19 v1 Algebraic Geometry

Abstract

Specht ideals are symmetric ideals in the polynomial ring generated by Specht polynomials associated with group representations. These ideals were previously studied for reflection groups of types AA and BB, where their inclusion relations and their varieties reflect rich combinatorial structures. In this paper, we extend this theory to type DD and the dihedral groups. Our results complete the combinatorial study of Specht ideals across all infinite families of essential real reflection groups.
