On Free Deformations of the Braid Arrangement [PDF]
, 1997 We classify the hyperplane arrangements between the cones of the braid arrangement and the Shi arrangement of type A n\Gamma1 which are free, in the sense of Terao. We also prove that the cones of the extended Shi arrangements of type A n\Gamma1 are free,

Labeling the Regions of the Type $C_n$ Shi Arrangement [PDF]
The Electronic Journal of Combinatorics, 2013 The number of regions of the type $C_n$ Shi arrangement in $\mathbb{R}^n$ is $(2n+1)^n$. Strikingly, no bijective proof of this fact has been given thus far. The aim of this paper is to provide such a bijection and use it to prove more refined results. We construct a bijection between the regions of the type $C_n$ Shi arrangement in $\mathbb{R}^n$ and ...

A Simple Bijection For The Regions Of The Shi Arrangement Of Hyperplanes [PDF]
, 1997 . The Shi arrangement Sn is the arrangement of affine hyperplanes in R n of the form x i \Gamma x j = 0 or 1, for 1 i ! j n. It dissects R n into (n+1) n\Gamma1 regions, as was first proved by Shi. We give a simple bijective proof of this result.

Simple-root bases for Shi arrangements
Journal of Algebra, 2015 In his affirmative answer to the Edelman-Reiner conjecture, Yoshinaga proved that the logarithmic derivation modules of the cones of the extended Shi arrangements are free modules. However, all we know about the bases is their existence and degrees. In this article, we introduce two distinguished bases for the modules. More specifically, we will define

A Description of the Minimal Elements of Shi Regions in Classical Weyl Groups [PDF]
, 2022 International audienceIn this extended abstract, we show how a bijection between parking functions and regions of the Shi arrangement from Athanasiadis and Linusson (in type An) and Armstrong, Reiner, and Rhoades (in type Bn, Cn, Dn) allows for the ...
