DESCRIPTION:Speakers: Ahmad Reza Haj Saeedi Sadegh (Dartmouth College)\n\n
 We utilize the differential geometry of Lie algebroids to define not-neces
 sarily elliptic Dirac operators. We will see that this construction is equ
 ivalent to a family of elliptic Dirac operators on source fibers of a Lie 
 groupoid. Using trace pairing with K-theory we give a fixed-point formula 
 for equivariant index of such Dirac operators. This result recovers Connes
  longitudinal index theorem for foliations\, and we give a new example for
  manifold with normal crossing divisors.\n\nhttps://math-events.uni-bonn.d
