A Duality Result for Moduli Spaces of Semistable Sheaves Supported on Projective Curves
We show that the moduli space M(r,c) of semistable sheaves on n-dimensional
projective space with support of dimension one, with multiplicity r and with
Euler characteristic c is isomorphic to M(r,-c).Comment: In the second version we rewrite the proofs in the language of
spectral sequences. The main results are unchanged. To appear in the

Relative Hilbert schemes and moduli spaces of torsion plane sheaves
We find certain relations between flag Hilbert schemes of points on plane
curves and moduli spaces of one-dimensional plane sheaves. We show that some of
these moduli spaces are unirational
