We prove that cubulated hyperbolic groups are virtually special. The proof relies on results of Haglund and Wise which also imply that they are linear groups, and quasi-convex subgroups are… (More)

The anaerobic degradative pathway for metabolism of 2,4,6-trinitrotoluene (TNT) by a consortium of Desulfovibrio spp. isolated from a creek sediment was studied. This consortium has the metabolic… (More)

We introduce a number of new tools for the study of relatively hyperbolic groups. First, given a relatively hyperbolic group G, we construct a nice combinatorial Gromov hyperbolic model space acted… (More)

We outline a rigorous algorithm, rst suggested by Casson, for determining whether a closed orientable 3-manifold M is hyperbolic, and to compute the hyperbolic structure, if one exists. The algorithm… (More)

If G is a group, a pseudocharacter f : G → R is a function which is “almost” a homomorphism. If G admits a nontrivial pseudocharacter f , we define the space of ends of G relative to f and show that… (More)

We prove some general results about quasi-actions on trees and define Property (QFA), which is analogous to Serre’s Property (FA), but in the coarse setting. This property is shown to hold for a… (More)

Suppose that all hyperbolic groups are residually finite. The following statements follow: In relatively hyperbolic groups with peripheral structures consisting of finitely generated nilpotent… (More)

An antigen-capture enzyme-linked immunosorbent assay employing rabbit and mouse antisera to Giardia lamblia cyst antigens was developed for the diagnosis of Giardia infection through detection of G.… (More)

Let M be a hyperbolic n–manifold whose cusps have torus crosssections. In [FM10], the authors constructed a variety of nonpositively and negatively curved spaces as “2π–fillings” of M by replacing… (More)

Motivated by a question of Gordon and Wilton, we consider the question of which collections of words are “virtually geometric”. In particular, we prove that some words (e.g. bbaaccabc) are not… (More)
