On the strong base locus of a projective variety
Edoardo Ballico, Maria Chiara Brambilla, Pierpaola Santarsiero
We introduce and study the base locus and the strong base locus of a projective variety X. The base locus of X parametrizes configurations of smooth points of X where the span of t…
Generic flatness of the cohomology of thickenings
Edoardo Ballico, Yairon Cid-Ruiz, Anurag K. Singh
We prove a generic flatness result for the cohomology of thickenings of a projective scheme that is smooth over a Noetherian domain containing a field of characteristic zero. Our s…
Higher rank bundles on Hopf surfaces
Edoardo Ballico, Elizabeth Gasparim
We show that all filtrable bundles on a Hopf surface must have jumps and we prove the existence of filtrable stable bundles on with any value of . On a somewhat oppo…
