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 ...

Two Generator Subalgebras Of Lie Algebras. [PDF]

open access: yes, 2007
In [14] Thompson showed that a finite group G is solvable if and only if every twogenerated subgroup is solvable (Corollary 2, p. 388). Recently, Grunevald et al.

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 ...
