Hyperbolic boundaries vs. hyperbolic groups
Michael Ben-Zvi, Jiayi Lou, Genevieve S. Walsh
The aim of these notes is to connect the theory of hyperbolic and relatively hyperbolic groups to the theory of manifolds and Kleinian groups. We also give definitions and many exa…
Folding-like techniques for CAT(0) cube complexes
Michael Ben-Zvi, Robert Kropholler, Rylee Alanza Lyman
In a seminal paper, Stallings introduced folding of morphisms of graphs. One consequence of folding is the representation of finitely-generated subgroups of a finite-rank free grou…
Boundaries of groups with isolated flats are path connected
Michael Ben-Zvi
A seminal result in geometric group theory is that a 1-ended hyperbolic group has a locally connected visual boundary. As a consequence, a 1-ended hyperbolic group also has a path…
Right-angled Artin group boundaries
Michael Ben-Zvi, Robert Kropholler
In all known examples of a CAT(0) group acting on CAT(0) spaces with non-homeomorphic CAT(0) visual boundaries, the boundaries are each not path connected. In this paper, we show t…
A Kochen-Specker theorem for integer matrices and noncommutative spectrum functors
Michael Ben-Zvi, Alexander Ma, Manuel Reyes
We investigate the possibility of constructing Kochen-Specker uncolorable sets of idempotent matrices whose entries lie in various rings, including the rational numbers, the intege…
