[HTML][HTML] The mathematics of lecture hall partitions

CD Savage - Journal of Combinatorial Theory, Series A, 2016 - Elsevier
Over the past twenty years, lecture hall partitions have emerged as fundamental
combinatorial structures, leading to new generalizations and interpretations of classical …

[HTML][HTML] Derangements, Ehrhart theory, and local h-polynomials

N Gustafsson, L Solus - Advances in Mathematics, 2020 - Elsevier
The Eulerian polynomials and derangement polynomials are two well-studied generating
functions that frequently arise in combinatorics, algebra, and geometry. When one makes an …

Enumeration of bounded lecture hall tableaux

S Corteel, JS Kim - arXiv preprint arXiv:1904.10602, 2019 - arxiv.org
Recently the authors introduced lecture hall tableaux in their study of multivariate little $ q $-
Jacobi polynomials. In this paper, we enumerate bounded lecture hall tableaux. We show …

Gorenstein properties and integer decomposition properties of lecture hall polytopes

T Hibi, MC Olsen, A Tsuchiya - arXiv preprint arXiv:1608.03934, 2016 - arxiv.org
Though much is known about ${\bf s} $-lecture hall polytopes, there are still many
unanswered questions. In this paper, we show that ${\bf s} $-lecture hall polytopes satisfy …

Some algebraic properties of lecture hall polytopes

P Brändén, L Solus - arXiv preprint arXiv:1911.12459, 2019 - arxiv.org
In this note, we investigate some of the fundamental algebraic and geometric properties of $
s $-lecture hall simplices and their generalizations. We show that all $ s $-lecture hall order …

Self dual reflexive simplices with Eulerian polynomials

T Hibi, MC Olsen, A Tsuchiya - Graphs and Combinatorics, 2017 - Springer
Abstract A lattice polytope PP is called reflexive if its dual P^ ∨ P∨ is a lattice polytope. The
property that PP is unimodularly equivalent to P^ ∨ P∨ does not hold in general, and in fact …

Hilbert bases and lecture hall partitions

MC Olsen - The Ramanujan Journal, 2018 - Springer
In the interest of finding the minimum additive generating set for the set of s s-lecture hall
partitions, we compute the Hilbert bases for the s s-lecture hall cones in certain cases. In …

Box polynomials of lattice simplices

N Gustafsson - 2018 - diva-portal.org
The box polynomial of a lattice simplex is a variant of the more well-known h∗-polynomial,
where the open fundamental parallelepiped is considered instead of the half-open. Box …

Polyhedral geometry for lecture hall partitions

MC Olsen - Algebraic and Geometric Combinatorics on Lattice …, 2019 - World Scientific
Lecture hall partitions are fundamental combinatorial objects which have been studied
extensively over the past two decades. These objects have produced new results, as well as …
