Supersolvable orders and inductively free arrangements

open access: yesOpen Mathematics, 2017
In this paper, we define the supersolvable order of hyperplanes in a supersolvable arrangement, and obtain a class of inductively free arrangements according to this order.

Gallery Posets of Supersolvable Arrangements [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
We introduce a poset structure on the reduced galleries in a supersolvable arrangement of hyperplanes. In particular, for Coxeter groups of type A or B, we construct a poset of reduced words for the longest element whose Hasse diagram is the graph of ...

On the geometry of real or complex supersolvable line arrangements

open access: yesJournal of Combinatorial Theory - Series A, 2016
Given a rank 3 real arrangement $\mathcal A$ of $n$ lines in the projective plane, the Dirac-Motzkin conjecture (proved by Green and Tao in 2013) states that for $n$ sufficiently large, the number of simple intersection points of $\mathcal A$ is greater than or equal to $n/2$.

The Counting Polynomial of a Supersolvable Arrangement

open access: yesAdvances in Mathematics, 1995
Let \(A\) be an arrangement of hyperplanes in a real finite dimensional vector space \(V\). The components of the complement of the union of the hyperplanes are called the chambers of \(A\). The counting polynomial \(\sum_{i \geq 0} a_i t^i\) of \(A\) in a chamber \(C\) is defined by setting \(a_i\) equal to the number of chambers which are separated ...

Worpitzky-compatible subarrangements of braid arrangements and cocomparability graphs

open access: yesComptes Rendus. Mathématique, 2021
The class of Worpitzky-compatible subarrangements of a Weyl arrangement together with an associated Eulerian polynomial was recently introduced by Ashraf, Yoshinaga and the first author, which brings the characteristic and Ehrhart quasi-polynomials into ...

Graded Linearity of Stanley–Reisner Ring of Broken Circuit Complexes

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
This paper introduces two new notions of graded linear resolution and graded linear quotients, which generalize the concepts of linear resolution property and linear quotient for modules over the polynomial ring A = k[x1, …, xn]. Besides, we compare graded linearity with componentwise linearity in general.
