Hermite normal forms and -vector
Takayuki Hibi, Akihiro Higashitani, Nan Li
Let $δ(\Pc) = (δ_0, δ_1,..., δ_d)$ be the -vector of an integral polytope $\Pc \subset \RR^N$ of dimension . Following the previous work of characterizing the -vectors wit…

Roots of Ehrhart polynomials arising from graphs
Tetsushi Matsui, Akihiro Higashitani, Yuuki Nagazawa +2
Several polytopes arise from finite graphs. For edge and symmetric edge polytopes, in particular, exhaustive computation of the Ehrhart polynomials not merely supports the conjectu…

Roots of Ehrhart polynomials of Gorenstein Fano polytopes
Takayuki Hibi, Akihiro Higashitani, Hidefumi Ohsugi
Given arbitrary integers and with , we construct a Gorenstein Fano polytope $\Pc \subset \RR^d$ of dimension such that (i) its Ehrhart polynomial $i(\…
