Strong solidity classification of Coxeter groups

Martín Blufstein, Katherine Goldman, Koichi Oyakawa

We prove the dichotomy that every Coxeter group either has a strongly solid group von Neumann algebra or contains the product of an infinite cyclic group and a free group of rank 2…

A new class of affine arrangements

Katherine Goldman, Jingyin Huang

We show that a certain class of affine hyperplane arrangements are by endowing their Falk complexes with an injective metric. This gives new examples of infinite …

-located locally -large complexes are aspherical

Katherine Goldman, Piotr Przytycki

We prove that -located locally -large simplicial complexes are aspherical.

The Deligne Complex for the Artin Group

Katherine Goldman, Amy Herron

We show that the piecewise Euclidean Moussong metric on the Deligne complex of the Artin group of type is . We do this by establishing a criteria for a compl…

2-dimensional Shephard groups

Katherine Goldman

The 2-dimensional Shephard groups are quotients of 2-dimensional Artin groups by powers of standard generators. We show that such a quotient is not if the powers…

CAT(0) and cubulated Shephard groups

Katherine Goldman

Shephard groups are common generalizations of Coxeter groups, Artin groups, and graph products of cyclic groups. Their definition is similar to that of a Coxeter group, but generat…

Simplicial pseudohyperplane arrangements give weak Garside groups

Katherine Goldman

In this note we connect the language of Bessis's Garisde categories with Salvetti's metrical-hemisphere complexes in order to find new examples of weak Garside groups. As our main…

The conjecture and acylindrical hyperbolicity for relatively extra-large Artin groups

Katherine Goldman

Let be an Artin group with defining graph . We introduce the notion of being extra-large relative to a family of arbitrary parabolic subgroups. This generalizes a re…
