DESCRIPTION:Speaker: Olga Trapeznikova\nhosted by Tamas Hausel\nAbstract: T
 he Verlinde formula\, an expression for the Hilbert function of the moduli
  spaces of vector bundles on Riemann surfaces\, is one of the most beautif
 ul results in enumerative geometry. In this talk\, I will describe a gen
 eralisation of this result in the case of the moduli space of rank-2 parab
 olic bundles: a calculation of Euler characteristics of universal vector b
 undles. The result is motivated by the formula of Teleman and Woodward f
 or the index of K-theory classes over the moduli stack of bundles on Riema
 nn surfaces. The approach uses a wall-crossing technique and the tautolog
 ical Hecke correspondence.
