Nathaniel Libman, Weston Miller
We prove that the -Ehrhart series of a hyperplane slice of a cube is a rational function with an explicit denominator that satisfies -reciprocity, confirming a conjecture of…

Combinatorics and Representation Theory of Special Cases of Chern Plethysm
Nathaniel Libman, Gidon Orelowitz
Chern plethysm (introduced by Billey, Rhoades, and Tewari) is a geometric way to produce Schur positive symmetric polynomials. We present combinatorial interpretations for the Schu…
