SUMMARY:Workshop / Seminar:RTG SEMINAR GeometryTopologyDynamics:  TWO INVARIANTS OF TYPE-PRESERVING REPRESENTATIONS AND APPLICATIONS
DESCRIPTION:Abstract:  We investigate the representations of surface groups into PSL(2\, R). For a closed surface\, by the classical result of Goldman\, the Euler class provides a complete classification of the connected components of the character variety. However\, describing these components becomes more subtle when considering the type-preserving representations for punctured surfaces. In this talk\, I will introduce two invariants of type-preserving representations that characterize the connected components. As an application\, I will show the existence of totally hyperbolic representations\, giving a negative answer to a question of Bowditch. I will also discuss the relation between the existence of such representations and the mapping class group action on the relative character variety.
