MARTIN BOBB - Euler Class Zero Representations and the Torelli Group
Friday, January 27, 2023
4:00-5:20 PM
3866 East Hall Map
The surface group representations of Euler class zero into PSL(2,R) are those which are deformations of diagonal (reducible) representation. Marche'-Wolff showed that the mapping class group acts ergodically on these representations with the strange exception of genus 2. We explore the infinitesimal data describing a deformation from a diagonal representation to an irreducible representation, and examine how the Torelli group acts on these deformations. Joint with James Farre.
