An explicit formula for the Hilbert series of a partial flag variety
Wayne A. Johnson
For a semisimple, simply-connected linear algebraic group, , and parabolic subgroup, , we use the fact that the Hilbert polynomial of the equivariant embedding of…

An Euler operator approach to Ehrhart series
Wayne A. Johnson
We use the ordinary Euler operator to compute the Ehrhart series for an arbitrary lattice polytope. The resulting formula involves the coefficients of the Ehrhart polynomial, combi…

A multi-variate generating function for the Weyl Dimension Formula
Wayne Johnson
We present a closed form for a multi-variate generating function for the dimensions of the irreducible representations of a semisimple, simply connected linear algebraic group over…
