DESCRIPTION:The first two parts of my talk will consist of independent sur
 veys of exciting theories.<br>1. I will discuss the theory of&nbsp\;"bound
 ary representations"\, which consists of the study of a class of unitary r
 epresentations arising naturally in geometric group theory.<br>2. I will d
 escribe the deformation theory of a right-angled Coxeter group W\, known a
 s the Iwahori-Hecke algebra H.<br>Later I will combine the two and focus o
 n&nbsp\;the boundary representation of W and explain how it deforms into a
  representation of H.<br>If time permits\, I will relate the above to the 
 boundary representations of groups which act on hyperbolic buildings.<br><
 br>Based on a joint work with Jan Dymara.<br><br>
