A remark on du Val linear systems
Enrico Arbarello
Let , be the genus du Val linear system on a Halphen surface of index . We prove that the Clifford index is constant on smooth curves . Let…
Singularities of Bridgeland moduli spaces for K3 categories: an update
Enrico Arbarello, Giulia Saccà
This survey is a continuation of the study undertaken in \cite{AS18}. We examine the local structure of Bridgeland moduli spaces $M_σ(v,\D)$, where the relevant triangulated catego…
Characterizing Jacobians via the KP equation and via flexes and degenerate trisecants to the Kummer variety: an algebro-geometric approach
Enrico Arbarello, Giulio Codogni, Giuseppe Pareschi
This paper is withdrawn since we found a flaw in the proof of Theorem 4, asserting that the base locus of the complete linear system of an ample line bundle on a complex abelian va…
Rank two vector bundles on polarised Halphen surfaces and the Gauss-Wahl map for du Val curves
Enrico Arbarello, Andrea Bruno
A genus-g du Val curve is a degree-3g plane curve having 8 points of multiplicity g, one point of multiplicity g-1, and no other singularity. We prove that the corank of the Gauss-…
Explicit Brill-Noether-Petri general curves
Enrico Arbarello, Andrea Bruno, Gavril Farkas +1
Let be the points in with coordinates $$(-2,3),(-1,-4),(2,5),(4,9),(52,375), (5234, 37866),(8, -23), (43, 28…
On hyperplane sections of K3 surfaces
Enrico Arbarello, Andrea Bruno, Edoardo Sernesi
Let C be a Brill-Noether-Petri curve of genus g\geq 12. We prove that C lies on a polarized K3 surface, or on a limit thereof, if and only if the Gauss-Wahl map for C is not surjec…
