Picard bundles and Twisted Picard bundles on the Jacobian of a curve
Usha N. Bhosle
Let denote an irreducible projective curve with at most nodes as singularities and defined over an algebraically closed field of characteristic zero. We study the restriction o…
Hitchin maps and parabolic Hitchin maps on the moduli spaces of Hitchin sheaves on nodal curves
Usha N. Bhosle
We study the Hitchin maps on the moduli spaces of Hitchin sheaves and parabolic Hitchin sheaves on a nodal integral curve . We study their fibres, the BNR correspondences and th…
Brauer and Picard groups of moduli spaces of parabolic vector bundles on a real curve
Usha N. Bhosle, Indranil Biswas
We determine the Brauer group and Picard group of the moduli space of stable parabolic vector bundles of rank with determinant on a real curve of arit…
Poincaré bundle for the fixed determinant moduli space on a nodal curve
Usha N. Bhosle
Let be an integral nodal projective curve of arithmetic genus with nodes defined over an algebraically closed field and a nonsingular closed point of .…
Projective Poincaré and Picard bundles for moduli spaces of vector bundles over nodal curves
C. Arusha, Usha N. Bhosle, Sanjay Kumar Singh
Let be the moduli space of stable vector bundles of rank with determinant where is a fixed line bundle of degree over a nodal curve . We prove th…
Moduli spaces of vector bundles on a singular rational ruled surface
Usha N. Bhosle, Indranil Biswas
We study moduli spaces parametrizing slope semistable vector bundles of rank and fixed Chern classes on a ruled surface whose base is a rational nod…
