Ulrich bundles on smooth toric threefolds with Picard number $2$

Debojyoti Bhattacharya, Francesco Malaspina

In this paper, we study Ulrich bundles on smooth toric threefolds with Picard number $2$ , namely $P (O_{P^{2}} (a_{0}) \oplus O_{P^{2}} (a_{1}))$ …

'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…

Castelnuovo-Mumford Regularity over Scrolls and Splitting Criteria

F. Malaspina, G. Sankaran

We introduce and study a notion of Castelnuovo-Mumford regularity suitable for scrolls obtained as projectivisations of sums of line bundles on $P^{m}$ . We show that this is…

On Primitive Ulrich Bundles over a few projective varieties with Picard number two

Francesco Malaspina

We introduce the notion of primitive Ulrich bundle in a smooth projective variety. We motivate this notion and give a cohomological characterization in the case of the degree $6$ f…
