 i spaces of bundles on curves - Heinloth\, J (Amsterdam)

DESCRIPTION:For moduli spaces of vector bundles on curves and some moduli 
 spaces of Higgs bundles\, it is possible to compute their cohomology group
 s in a geometric way\, i.e.\, one can describe the space by a cut-and-past
 e procedure in terms of cells and symmetric products of the base curve.  \
 nThis gives a rather explicit description of the "motive" of the space.\n\
 nFor moduli space of vector bundles this is due to Behrend and Dhillon\, r
 elying on an argument of Bifet\, Ghione\, and Letizia.\nWe will try to giv
 e an introduction to this point of view on cohomology calcuations for modu
 li spaces.\n\n
