Local Tameness and Ends of Groups

Rita Gitik

We investigate connections between local tameness of a group and a number of its ends.

On Products of Closed Subsets in Free Groups

Rita Gitik, Eliyahu Rips

We present examples of closed subsets of a free group such that their product is not closed in the profinite topology. We discuss how to characterize a subset of a free group which…

On Geodesic Triangles in Hyperbolic Plane

Rita Gitik

Let M be an orientable hyperbolic surface without boundary and let $γ$ be a closed geodesic in M. We prove that any side of any triangle formed by distinct lifts of $γ$ in H2 is sh…

On Local Tameness of Certain Graphs of Groups

Rita Gitik

Let $G$ be the fundamental group of a finite graph of groups with Noetherian edges and locally tame vertices. We prove that $G$ is locally tame. It follows that if a finitely prese…
