On the projective normality of Ulrich bundles on some low-dimensional varieties
Valerio Buttinelli
We study the projective normality of the projective bundle of an Ulrich vector bundle embedded through the complete linear system of its tautological line bundle. The focus will be…

Positivity of Ulrich bundles in the ample and free case
Valerio Buttinelli
We study the positivity of an Ulrich vector bundle defined with respect to a globally generated ample line bundle. First we prove a generalization of a Lopez theorem on the first C…
