The group law of Picard stacks via matrices
Cristiana Bertolin, Federica Galluzzi
Let S be a site. We show that the 2-stack of strictly commutative Picard stacks over S is algebraic, i.e. it is 2-equivalent to the 2-stack of 2-algebras for an adequate algebraic…
A note on divisorial correspondences of extensions of abelian schemes by tori
Cristiana Bertolin, Federica Galluzzi
Let S be a locally noetherian scheme and consider two extensions G_1 and G_2 of abelian S-schemes by S-tori. In this note we prove that the fppf-sheaf Corr _S(G_1,G_2) of divisoria…
Brauer groups of 1-motives
Cristiana Bertolin, Federica Galluzzi
Over a normal base scheme, we prove the generalized Theorem of the Cube for 1-motives and that a torsion class of the group H^2_ét(M,G_m)$ of a 1-motive M, whose pull-back via the…
Stability of Rank 2 Ulrich Bundles on Projective K3 Surfaces
Gianfranco Casnati, Federica Galluzzi
Let be a non-degenerate surface of degree , where . In this paper we deal with Ulrich bundles on of rank . We deal with their st…
The Nori-Hilbert scheme is not smooth for 2-Calabi Yau algebras
Raf Bocklandt, Federica Galluzzi, Francesco Vaccarino
Let be an algebraically closed field of characteristic zero and let be a finitely generated algebra. The Nori - Hilbert scheme of , parameterizes left ideals of codi…
A new family of algebras whose representation schemes are smooth
Alessandro Ardizzoni, Federica Galluzzi, Francesco Vaccarino
We give a necessary and sufficient smoothness condition for the scheme parameterizing the n-dimensional representations of a finitely generated associative algebra over an algebrai…
