van Kampen's Theorem and Group actions on Trees
Abstract: Starting with van Kampen's theorem we trace how a group splitting gives rise to an action on a tree. We will survey (but probably not prove)
converses and related structure theorems for groups one can obtain when the group acts on a tree. This talk will be accessible to anyone with a familiarity with van Kampen's theorem.
