 >Selberg's Trace Formula in operator K-theory</a>\nby Haluk Sengun (Univer
 sity of Sheffield) as part of Noncommutative geometry in NYC\n\n\nAbstract
 \nSelberg introduced his celebrated trace formula in 1956. Since\nthen\, t
 he trace formula has become an indispensable tool in number\ntheory\, with
  spectacular applications to the Langlands program. After an\nexposition o
 f the trace formula\, I will present an identity in the\nsetting of K-theo
 ry of group C*-algebras that is an analogue of the\ntrace formula. Time re
 maining\, I will exhibit how one can derive the\nindex theoretic version o
 f the trace formula (due to Barbasch and\nMoscovici) from our identity via
  the theory of higher indices.\n\nThis is joint work with Bram Mesland (Le
 iden) and Hang Wang (Shanghai).\n
