Gorenstein graphic matroids

Takayuki Hibi, Michał Lasoń, Kazunori Matsuda +2

The toric variety of a matroid is projectively normal, and therefore it is Cohen-Macaulay. We provide a complete graph-theoretic classification when the toric variety of a graphic…

Induced matching numbers of finite graphs and edge ideals

Takayuki Hibi, Hiroju Kanno, Kazunori Matsuda

Let $G$ be a finite simple graph on the vertex set $V (G) = {x_{1}, \dots, x_{n}}$ and $I (G) \subset K [V (G)]$ its edge ideal, where $K [V (G)]$ is the polynomial ring in $x_1, \ldots,…

Regularity and $a$ -invariant of Cameron--Walker graphs

Takayuki Hibi, Kyouko Kimura, Kazunori Matsuda +1

Let $S$ be the polynomial ring over a field $K$ and $I \subset S$ a homogeneous ideal. Let $h (S / I, λ)$ be the $h$ -polynomial of $S / I$ and $s = deg h (S / I, λ)$ the degree of $…
