Hodge conjecture for the moduli space of semi-stable sheaves over a nodal curve.

In this article, we prove the Hodge conjecture for a desingularization of the moduli space of rank 2, semi-stable, torsion-free sheaves with fixed odd degree determinant over a very general irreducible nodal curve of genus at least 2. We also compute the algebraic Poincaré polynomial of the associated cohomology ring. [ABSTRACT FROM AUTHOR]
