Immersions of complexes of groups
Abstract: The theory of complexes of groups allows one to study generalizations of free group actions on simply connected polyhedral complexes. In this talk, we discuss motivations of the theory, including applications to recent work by Groves—Manning and Einstein—Groves extending Agol’s theorem beyond the setting of geometric actions. We will also introduce a new notion of an immersion of complexes of groups and state our main result on locally convex immersions into non-positively curved complexes of groups.
