Singularities of secant varieties from a Hodge theoretic perspective

Sebastian Olano, Debaditya Raychaudhury, Lei Song

We study the singularities of secant varieties of smooth projective varieties using methods from birational geometry when the embedding line bundle is sufficiently positive. More p…

On varieties with Ulrich twisted conormal bundles

Vincenzo Antonelli, Gianfranco Casnati, Angelo Felice Lopez +1

We study varieties $X \subset P^{r}$ such that is $N_{X}^{*} (k)$ is an Ulrich vector bundle for some integer $k$ . We first prove that such an $X$ must be a curve. Then we give several ex…

On varieties with Ulrich twisted tangent bundles

Angelo Felice Lopez, Debaditya Raychaudhury

We study varieties $X \subseteq P^{N}$ of dimension $n$ such that $T_{X} (k)$ is an Ulrich vector bundle for some $k \in Z$ . First we give a sharp bound for $k$ in the c…
