Reflections on branched covers
Grigori Avramidi, Boris Okun, Kevin Schreve
A flag complex determines a locally CAT(0) cube complex with the links of all vertices isomorphic to . The fundamental group of is the commutator subgroup of the…
Embedding complexes into pseudomanifolds
Kasia Jankiewicz, Kevin Schreve
We show that for every finite -dimensional simplicial complex is a deformation retract of a -dimensional pseudomanifold with boundary. Moreover, it embeds as a…
Conformal dimension bounds, Pontryagin sphere boundaries, and algebraic fibering of right-angled Coxeter groups
Christopher H. Cashen, Pallavi Dani, Kevin Schreve +1
We introduce a graph-theoretic condition, called --branching, that ensures a combinatorial round tree with controlled branching parameters can be quasi-isometrically embedde…
Cyclic orders and actions of Leary--Minasyan groups on coarse spaces
Arka Banerjee, Kevin Schreve
We show that for , there are torsion-free CAT(0) groups with visual boundaries that embed into but which are not virtually the fundamental group of a compact aspher…
L^2-Betti numbers of branched covers of hyperbolic manifolds
Grigori Avramidi, Boris Okun, Kevin Schreve
We show that Gromov-Thurston branched covers satisfy the Singer conjecture whenever the degree of the cover is not divisible by a finite set of primes determined by the base manifo…
Edge subdivisions and the -homology of right-angled Coxeter groups
Grigori Avramidi, Boris Okun, Kevin Schreve
If is a flag triangulation of , then the Davis complex for the associated right-angled Coxeter group is a contractible -manifold. A special case of a co…
