Higher Teichmüller-Thurston theory is the study of a specific component of representations of a surface group of genus g in PSL(n,R). Teichmüller theory depends on a parameter: the genus g of the surface. Higher Teichmüller-Thurston introduces a new paramater n so that classical theory corresponds to n=2. Teichmüller theory is a crossroad between dynamics, complex analysis, spectral theory, geomet ...
