Abstract: | The first two parts of my talk will consist of independent surveys of exciting theories.
1. I will discuss the theory of "boundary representations", which consists of the study of a class of unitary representations arising naturally in geometric group theory. 2. I will describe the deformation theory of a right-angled Coxeter group W, known as the Iwahori-Hecke algebra H. Later I will combine the two and focus on the boundary representation of W and explain how it deforms into a representation of H. If time permits, I will relate the above to the boundary representations of groups which act on hyperbolic buildings. Based on a joint work with Jan Dymara. |
