Leighton's Theorem: extensions, limitations, and quasitrees

Martin R. Bridson, Sam Shepherd

Leighton's Theorem states that if there is a tree $T$ that covers two finite graphs $G_{1}$ and $G_{2}$ , then there is a finite graph $G^$ that is covered by $T$ and covers both $G…

Quasi-isometric rigidity for graphs of virtually free groups with two-ended edge groups

Sam Shepherd, Daniel J. Woodhouse

We study the quasi-isometric rigidity of a large family of finitely generated groups that split as graphs of groups with virtually free vertex groups and two-ended edge groups. Let…
