Using flat geometry to study surface group representations

Jeudi 27 février 14:00-15:00 - Aaron Fenyes - IHES

Résumé : Adding geometric structure to a surface can help you study the
representations of its fundamental group. I’ll show you how a special
kind of flat structure, called a half-translation structure, can help
you study representations into SL(2,C). Characterizing Anosov
representations and calculating shear-bend coordinates are the main
applications I plan to cover.
