Sahana Balasubramanya: Quasi-parabolic group actions on hyperbolic spaces
Thursday, 03.12.2020 10:30 im Raum via Zoom
Gromov's classification of groups acting on hyperbolic spaces exactly
classifies the 5 different possibilities that can arise in this situation. Of
these, quasi- parabolic actions are the least understood and several questions
remain unanswered in this regard. In this talk, I will talk about the
motivation behind our work, and describe some known structural results related
to quasi-parabolic actions.
I will also talk about a new construction, developed by me, C.Abbott and
A.Rasmussen, that allows us to build quasi-parabolic actions for new groups.
This construction is a generalization of the work of
Caprace-Cornulier-Monod-Tessera from their paper 'Amenable hyperbolic groups'.
As a result, we are able to completely classify the quasi-parabolic actions of
certain groups on hyperbolic spaces.
