Torus action on the moduli spaces of torsion plane sheaves of multiplicity four

초록

We describe the torus fixed locus of the moduli space of stable sheaves with Hilbert polynomial 4m+1 on P-2. We determine the torus representation of the tangent spaces at the fixed points, which leads to the computation of the Betti and Hodge numbers of the moduli space. (C) 2014 Elsevier B.V.
