A Note on Parabolic Bundles on Nodal Curves
C. Arusha, Sanjay Kumar Singh
Mehta and Seshadri have proved that the set of equivalence classes of irreducible unitary representations of the fundamental group of a punctured compact Riemann surface, can be id…
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…
A Short Note on Self-Duality of Goppa Codes on Elliptic and Hyperelliptic Function Fields
Nupur Patanker, Sanjay Kumar Singh
In this note, we investigate Goppa codes which are constructed by means of Elliptic function field and Hyperelliptic function field. We also give a simple criterion for self-dualit…
Diagonal property of the symmetric product of a smooth curve
Indranil Biswas, Sanjay Kumar Singh
Let be an irreducible smooth projective curve defined over an algebraically closed field. We prove that the symmetric product has the diagonal property for all…
