$ℓ$ -away ACM line bundles on a nonsingular cubic surface

Debojyoti Bhattacharya, A. J. Parameswaran, Jagadish Pine

Let $X \subset P^{3}$ be a nonsingular cubic hypersurface. Faenzi (\cite{F}) and later Pons-Llopis and Tonini (\cite{PLT}) have completely characterized ACM line bundles over…

Ulrich bundles on cyclic coverings of projective spaces

A. J. Parameswaran, Jagadish Pine

We prove the existence of Ulrich bundles on cyclic coverings of $P^{n}$ of arbitrary degree $d$ . Given a relatively Ulrich bundle on a complete intersection subvariety, we c…
