Gorenstein properties and integer decomposition properties of lecture hall polytopes
Takayuki Hibi, McCabe Olsen, Akiyoshi Tsuchiya
Though much is known about -lecture hall polytopes, there are still many unanswered questions. In this paper, we show that -lecture hall polytopes satisfy the int…
Nonincreasing depth functions of monomial ideals
Kazunori Matsuda, Tao Suzuki, Akiyoshi Tsuchiya
Given a nonincreasing function such that (i) for all and (ii) if an…
Self dual reflexive simplices with Eulerian polynomials
Takayuki Hibi, McCabe Olsen, Akiyoshi Tsuchiya
A lattice polytope is called reflexive if its dual is a lattice polytope. The property that is unimodularly equivalent to $\mathcal{P…
Facets and volume of Gorenstein Fano polytopes
Takayuki Hibi, Akiyoshi Tsuchiya
It is known that every integral convex polytope is unimodularly equivalent to a face of some Gorenstein Fano polytope. It is then reasonable to ask whether every normal polytope is…
Flat -vectors and their Ehrhart polynomials
Takayuki Hibi, Akiyoshi Tsuchiya
We call the -vector of an integral convex polytope of dimension flat if the -vector is of the form , where . In this paper…
On the sign patterns of the coefficients of Hilbert polynomials
Akiyoshi Tsuchiya
We show that all sign patterns of the coefficients Hilbert polynomials of standard graded -algebras are possible.
