Bruhat order, rationally smooth Schubert varieties, and hyperplane arrangements [PDF]

open access: yes, 2010
We link Schubert varieties in the generalized flag manifolds with hyperplane arrangements. For an element of a Weyl group, we construct a certain graphical hyperplane arrangement.

Application of hyperplane arrangements to weight enumeration [PDF]

open access: yes, 2014
Many research in coding theory is focussed on linear error-correcting codes. Since these codes are subspaces, linear algebra plays a prominent role in studying them.

Jumping Numbers of Hyperplane Arrangements [PDF]

open access: yesCommunications in Algebra, 2010
M. Saito recently proved that the jumping numbers of a hyperplane arrangement depend only on the combinatorics of the arrangement. However, a formula in terms of the combinatorial data was still missing. In this note, we give a formula and a different proof of the fact that the jumping numbers of a hyperplane arrangement depend only on the ...

Group Actions on Hyperplane Arrangements [PDF]

open access: yes, 2012
In this dissertation, we will look at two families of algebras with connections to hyperplane arrangements that admit actions of finite groups. One of the fundamental questions to ask is how these decompose into irreducible representations. For the first

Projection volumes of hyperplane arrangements [PDF]

open access: yes, 2010
We prove that for any finite real hyperplane arrangement the average projection volumes of the maximal cones is given by the coefficients of the characteristic polynomial of the arrangement. This settles the conjecture of Drton and Klivans that this held

The face lattice of hyperplane arrangements

open access: yesDiscrete Mathematics, 1988
A finite set \({\mathcal H}\) of hyperplanes in \({\mathbb{R}}^ d\) is called an arrangement. It determines a partition of \({\mathbb{R}}^ d\) into open topological cells, the face lattice \(L({\mathcal H})\) of which is studied by the author. He shows \(L({\mathcal H})\) to be shellable. To \({\mathcal H}\) there is assigned a zonotope \(\tilde Z\) in

Electrical networks and hyperplane arrangements

open access: yesAdvances in Applied Mathematics, 2019
This paper studies \emph{Dirichlet arrangements}, a generalization of graphic hyperplane arrangements arising from electrical networks and order polytopes of finite posets. We generalize descriptions of combinatorial features of graphic arrangements to Dirichlet arrangements, including characteristic polynomials and supersolvability.

Hyperplane arrangements: computations and conjectures

open access: yesAdvanced Studies in Pure Mathematics, 2019
This paper provides an overview of selected results and open problems in the theory of hyperplane arrangements, with an emphasis on computations and examples. We give an introduction to many of the essential tools used in the area, such as Koszul and Lie algebra methods, homological techniques, and the Bernstein-Gelfand-Gelfand correspondence, all ...
