On Ulrich bundles on some decomposable threefold scrolls over
Maria Lucia Fania, Flaminio Flamini, Francesco Malaspina +1
The study of Ulrich bundles provides profound insights into the underlying geometry and derived categories of projective varieties supporting them, yet their existence and modular…
'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 on three dimensional scrolls
Maria Lucia Fania, Margherita Lelli-Chiesa, Joan Pons-Llopis
In this paper we construct Ulrich bundles of low rank on three-dimensional scrolls (with respect to the tautological line bundle). We pay special attention to the four types of thr…
aCM vector bundles on projective surfaces of nonnegative Kodaira dimension
Edoardo Ballico, Sukmoon Huh, Joan Pons-Llopis
In this paper we contribute to the construction of families of arithmetically Cohen-Macaulay (aCM) indecomposable vector bundles on a wide range of polarized surfaces $(X,\Oo_X(1))…
Ulrich bundles on smooth projective varieties of minimal degree
Marian Aprodu, Sukmoon Huh, Francesco Malaspina +1
We classify the Ulrich vector bundles of arbitrary rank on smooth projective varieties of minimal degree. In the process, we prove the stability of the sheaves of relative differen…
