Equivariant gamma-positivity of matroid Chow rings
Hsin-Chieh Liao
In this paper, we prove that the Chow ring and augmented Chow ring of a matroid are equivariantly -positive under the action of any group of automorphisms. Our approach provide…

Chow rings and augmented Chow rings of uniform matroids and their -analogs
Hsin-Chieh Liao
We study the Hilbert series and the representations of and on the (augmented) Chow rings of uniform matroids and -uniform matroid…

Stembridge codes, permutahedral varieties, and their extensions
Hsin-Chieh Liao
It is well known that the Eulerian polynomial is the Hilbert series of the cohomology of the permutahedral variety. Stanley obtained a formula showing that the cohomology carries a…
