Properly discontinuous actions versus uniform embeddings

Kevin Schreve

Whenever a finitely generated group $G$ acts properly discontinuously by isometries on a metric space $X$ , there is an induced uniform embedding (a Lipschitz and uniformly proper m…

Nonplanar graphs in boundaries of CAT(0) groups

Kevin Schreve, Emily Stark

Croke and Kleiner constructed two homeomorphic locally CAT(0) complexes whose universal covers have visual boundaries that are not homeomorphic. We construct two homeomorphic local…

Action dimensions of some simple complexes of groups

Michael W. Davis, Giang Le, Kevin Schreve

The action dimension of a discrete group $G$ is the minimum dimension of contractible manifold that admits a proper $G$ -action. We compute the action dimension of the direct limit…

Coxeter Groups, Ruins, and Weighted $L^{2}$ -cohomology

Wiktor Mogilski, Kevin Schreve

Given a Coxeter system $(W, S)$ and a multiparameter $q$ of real numbers indexed by $S$ , one can define the weighted $L^{2}$ -cohomology groups and associate to them a nonnega…
