The study of spaces of complex structures on a Riemann surface, the so-called Moduli space and Teichmüller space is a classical and well-studied area of mathematics, with relations and interconnections with  different areas of mathematics and also  theoretical physics.  In the case of surfaces with genus at least two, complex structures can be uniformized to hyperbolic structures, which are discrete, faithful representations of surface groups in the group of  isometries of the hyperbolic plane. A natural generalization is to consider surface group representations in other semisimple Lie groups.  In the last few years, spectacular advances have been made towards generalizing existing tools and techniques to the study of these representations, and their moduli spaces. Remarkably, in many cases there is a natural generalization of discrete, faithful representations which provides an analogue of Teichmüller space. Our program shall focus on two perspectives:

  1. The dynamic point of view, leading to Anosov surface group representations (in the sense of Labourie).
  2. The complex geometric point of view coming from complex projective structures on surfaces.

  The program may be thought of as a focused follow-up of two programs held at ICTS in November 2017: 

  1. Geometry, groups and dynamics (GGD-2017)
  2. Surface group representations and geometric structures (SGGS)

While the 2017 program had some introductory talks on the subject of “Higher Teichmuller theory” (also known as the theory of surface group representations in semi-simple Lie groups of higher rank), the purpose of the present program is to take the subject further. 

We expect that a number of the participants of the former program (GGD and SGGS), particularly some of the younger participants, will be focusing on this area in their research. The follow-up program would have these researchers as the target audience. The meeting will thus be aimed at a specialised audience, and only focused researchers and scholars of these areas with prior background in these subjects will be included.

Accommodation for outstation/non-local participants will be provided at our on campus ICTS guest house.
