$\Cal M_{15}$ is rationally connected
Andrea Bruno, Alessandro Verra
The authors prove that $\Cal M_{15}$ is rationally connected
The unirationality of the moduli space of curves of genus
Alessandro Verra
The new result is the unirationality of the moduli space of curves of genus 14. The method applies to lower genus.
Quaternionic pryms and Hodge classes
B. van Geemen, A. Verra
Abelian varieties of dimension 2n on which a definite quaternion algebra acts are parametrized by symmetrical domains of dimension n(n-1)/2. Such abelian varieties have primitive H…
The degree of the Gauss map for a general Prym Theta Divisor
A. Verra
Refereed version to appear on Journal of Algebraic Geometry. Unchanged content. Strongly ameliorated presentation thanks to referee's action.
On the theta divisor of SU(2,1)
Sonia Brivio, Alessandro Verra
Let SU(2,1) be the moduli space of stable rank two vector bundles having fixed determinant of odd degree over a compact Riemann surface C. In this paper it is shown that the Theta…
