Resumen de Stability of rank two Ulrich bundles on projective K3 surfaces

Gianfranco Casnati, Federica Galluzzi

• Let F⊆PN be a K3 surface of degree 2a, where a≥2. In this paper we deal with Ulrich bundles on F of rank 2. We deal with their stability and we construct K3 surfaces endowed with families of non-special Ulrich bundles of rank 2 for each a≥2.
