On the existence of Ulrich bundles on geometrically ruled surfaces

Gianfranco Casnati

Let $S$ be a geometrically ruled surface with invariant $e$ on a curve $C$ . We deal with Ulrich line bundles and $μ$ -stable special Ulrich bundles of rank $2$ on $S$ when $e \geq 0$ ,…

Special Ulrich bundles on non-special surfaces with $p_{g} = q = 0$

Gianfranco Casnati

Let $S$ be a surface with $p_{g} (S) = q (S) = 0$ and endowed with a very ample line bundle $O_{S} (h)$ such that $h^{1} (S, O_{S} (h)) = 0$ . We show that $S$ supports specia…

Stability of Rank 2 Ulrich Bundles on Projective K3 Surfaces

Gianfranco Casnati, Federica Galluzzi

Let $F \subseteq P^{a + 1}$ be a non-degenerate $K 3$ surface of degree $2 a$ , where $a \geq 2$ . In this paper we deal with Ulrich bundles on $F$ of rank $2$ . We deal with their st…

Rank two aCM bundles on general determinantal quartic surfaces in $P^{3}$

Gianfranco Casnati

Let $F \subseteq P^{3}$ be a smooth determinantal quartic surface which is general in the Nöther-Lefschetz sense. In the present paper we give a complete classification of loc…

Examples of rank two aCM bundles on smooth quartic surfaces in $P^{3}$

Gianfranco Casnati, Roberto Notari

Let $F \subseteq P^{3}$ be a smooth quartic surface and let $O_{F} (h) := O_{P^{3}} (1) \otimes O_{F}$ . In the present paper we classify locally fre…
