Ulrich bundles on double covers of projective spaces
N. Mohan Kumar, Poornapushkala Narayanan, A. J. Parameswaran
In this article, we prove that any smooth projective variety which is a double cover of the projective space () admits an Ulrich bundle. When , we…
Ulrich line bundles on double planes
A. J. Parameswaran, Poornapushkala Narayanan
Consider a smooth complex surface which is a double cover of the projective plane branched along a smooth curve of degree . In this article, we study the geo…
On multiplicity of spectrum for Anderson type operators with higher rank perturbations
Anish Mallick, P A Narayanan
Here, we focus on Anderson type operators over infinite graphs where the randomness acts through higher rank perturbations. We show that for special family of graphs, the operator…
Semistability of Lazarsfeld-Mukai bundles via parabolic structures
Poornapushkala Narayanan
Our aim in this article is to produce new examples of semistable Lazarsfeld- Mukai bundles on smooth projective surfaces using the notion of parabolic vector bundles. In partic…
Lazarsfeld-Mukai Reflexive Sheaves and their Stability
Poornapushkala Narayanan
Consider an ample and globally generated line bundle on a smooth projective variety of dimension over . Let be a smooth divisor in the complete li…
On the Semistability of certain Lazarsfeld-Mukai bundles on Abelian surfaces
Poornapushkala Narayanan
Let be the Jacobian of a genus 2 curve over and be the associated Kummer surface. Consider an ample line bundle $L=O(m\widetilde{\mat…
