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 $(n, d, n + 1)$ on a Petri curve $X$ of genus $g \geq 2$ . 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 $U^{'}$ of semistable vector bundles of rank $n$ and degree $d$ on an irreducible nodal curve $Y$ and show that $U^{'}$ is locally factori…
