Mathematische Nachrichten, 2018, vol. 291, issue 1, 7-23

Abstract: We compute Betti numbers of both the components of the moduli space of rank 2 semi†stable torsion†free sheaves with fixed determinant over a reducible nodal curve with two smooth components intersecting at a node. We also compute the intersection Betti numbers of the moduli space.
