Stability and deformations of generalised Picard sheaves

I. Biswas, L. Brambila-Paz, P. E. Newstead

Let $C$ be a smooth irreducible complex projective curve of genus $g \geq 2$ and $M$ the moduli space of stable vector bundles on $C$ of rank $n$ and degree $d$ with $g cd (n, d) = 1$ .…

Nonemptiness and smoothness of twisted Brill-Noether loci

George H. Hitching, Michael Hoff, Peter E. Newstead

Let $V$ be a vector bundle over a smooth curve $C$ . In this paper, we study twisted Brill--Noether loci parametrising stable bundles $E$ of rank $n$ and degree $e$ with the propert…

Seshadri constants and Grassmann bundles over curves

Indranil Biswas, Krishna Hanumanthu, D. S. Nagaraj +1

Let $X$ be a smooth complex projective curve, and let $E$ be a vector bundle on $X$ which is not semistable. For a suitably chosen integer $r$ , let $Gr (E)$ be the Grassmann…
