't Hooft bundles on the complete flag threefold and moduli spaces of instantons

Vincenzo Antonelli, Francesco Malaspina, Simone Marchesi +1

In this work we study the moduli spaces of instanton bundles on the flag twistor space $F := F (0, 1, 2)$ . We stratify them in terms of the minimal twist supporting global sections and…

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…
