SUMMARY:Intersection cohomology of the moduli of of 1-dimensional sheaves and the moduli of Higgs bundles
DESCRIPTION:Speaker: Junliang Shen\, MIT\n\nIn general, the topology of the moduli space of semistable sheaves on an algebraic variety relies heavily on the choice of the Euler characteristic of the sheaves. We show a striking phenomenon that, for the moduli of 1-dimensional semistable sheaves on a toric del Pezzo surface (e.g. P^2), or the …
