On an explicit correspondence between \(nbc\)-basis, chambers and minimal complex for real supersolvable arrangements [PDF]

open access: yesAustralas. J Comb., 2019
The authors give a very natural description of the bijections between the set of cells in the minimal CW-complex homotopy equivalent to the complement of a complexified real supersolvable arrangement $\mathcal{A}$, the \textbf{nbc}-basis (non broken circuit basis) of the Orlik-Solomon algebra associated to $\mathcal{A}$ and the set of chambers of ...

Supersolvable simplicial arrangements [PDF]

open access: yesAdvances in Applied Mathematics, 2019
Simplicial arrangements are classical objects in discrete geometry. Their classification remains an open problem but there is a list conjectured to be complete at least for rank three. A further important class in the theory of hyperplane arrangements with particularly nice geometric, algebraic, topological, and combinatorial properties are the ...

The Active Bijection between Regions and Simplices in Supersolvable Arrangements of Hyperplanes [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2006
Comparing two expressions of the Tutte polynomial of an ordered oriented matroid yields a remarkable numerical relation between the numbers of reorientations and bases with given activities. A natural activity preserving reorientation-to-basis mapping compatible with this relation is described in a series of papers by the present authors.

Simple Geometric Characterization of Supersolvable Arrangements

open access: yesRocky Mountain Journal of Mathematics, 2001
An arrangement of hyperplanes is a finite collection of \(\mathbb{C}\)-linear subspaces of dimension \(d-1\) in \(\mathbb{C}^d.\) Let \(A\) be an arrangement in \(\mathbb{C}^3\) and \(A^*\) be the natural projective arrangements in \(\mathbb{C}\mathbb{P}^2\) associated to it.

On arrangements of hyperplanes from connected subgraphs

open access: yes, 2022
We investigate arrangements of hyperplanes whose normal vectors are given by connected subgraphs of a fixed graph. These include the resonance arrangement and certain ideal subarrangements of Weyl arrangements.

Inductive and divisional posets

open access: yes, 2023
We call a poset factorable if its characteristic polynomial has all positive integer roots. Inspired by inductive and divisional freeness of a central hyperplane arrangement, we introduce and study the notion of inductive posets and their superclass of ...
