Ulrich bundles on smooth toric threefolds with Picard number
Debojyoti Bhattacharya, Francesco Malaspina
In this paper, we study Ulrich bundles on smooth toric threefolds with Picard number, namely …
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 . 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 f…
Castelnuovo-Mumford Regularity and Splitting Criteria for Logarithmic Bundles over Rational Normal Scroll Surfaces
Roberta Di Gennaro, Francesco Malaspina
We introduce and study a notion of Castelnuovo-Mumford regularity suitable for rational normal scroll surfaces. In this setting we prove analogs of some classical properties. We pr…
'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 . We stratify them in terms of the minimal twist supporting global sections and…
Ulrich bundles of arbitrary rank on Segre-Veronese varieties
Francesco Malaspina
We generalize the results by Eisenbud and Schreyer about Ulrich bundles over Veronese varieties to Segre-Veronese varieties. We discuss the range where we have natural cohomology a…
