On coherent systems of type (n,d,n+1) on Petri curves
U. N. Bhosle, L. Brambila-Paz, P. E. Newstead
We study coherent systems of type on a Petri curve of genus . We describe the geometry of the moduli space of such coherent systems for large values of the p…

Stable real algebraic vector bundles over a Klein bottle
Usha N. Bhosle, Indranil Biswas
Let X be a geometrically connected smooth projective curve of genus one, defined over the field of real numbers, such that X does not have any real points. We classify the isomorph…

Picard groups of the moduli spaces of semistable sheaves I
Usha N Bhosle
We compute the Picard group of the moduli space of semistable vector bundles of rank and degree on an irreducible nodal curve and show that is locally factori…
