SUMMARY:Math Seminar Series
DESCRIPTION:
 Mathematical Physics and Operator Algebras\n
 \n
 Krishnendu Kahn from the University of Iowa will 
 be speaking.\n
 \n
 The presentation is titled 
 "Fundamental groups of certain property (T) 
 factors."\n
 \n
 This is a virtual meeting.\n
 \n
 The 
 description is as follows:\n
 \n
 Calculation 
 of fundamental groups of type II1 factor is, 
 in general, an extremely hard and central problem 
 in the field of von Neumann algebras. In 
 this direction, a conjecture due to A. Connes 
 states that the fundamental group of the group 
 von Neumann algebra L(Γ) associated 
 to any icc property (T) group Γ is trivial. 
 Up to now, there was no single example of 
 property (T) group factor satisfying the conjecture. 
 In this talk, I shall provide the first 
 examples of property (T) group factors with 
 trivial fundamental group. This talk is based 
 on a joint work with Ionut Chifan, Sayan 
 Das and Cyril Houdayer.\n\n
