Mirror Quintics, discrete symmetries and Shioda Maps
Gilberto Bini, Bert van Geemen, Tyler L. Kelly
In a recent paper, Doran, Greene and Judes considered one parameter families of quintic threefolds with finite symmetry groups. A surprising result was that each of these six famil…
Siegel metric and curvature of the moduli space of curves
Elisabetta Colombo, Paola Frediani
We study the curvature of the moduli space M_g of curves of genus g with the Siegel metric induced by the period map. We give an explicit formula for the holomorphic sectional curv…
A geometrical approach to Gordan--Noether's and Franchetta's contributions to a question posed by Hesse
Alice Garbagnati, Flavia Repetto
Hesse claimed that an irreducible projective hypersurface in $\PP^n$ defined by an equation with vanishing hessian determinant is necessarily a cone. Gordan and Noether proved that…
Symplectic Automorphisms on Kummer Surfaces
Alice Garbagnati
Nikulin proved that the isometries induced on the second cohomology group of a K3 surface by a finite abelian group of symplectic automorphisms are essentially unique. More…
Ample subvarieties and rationally connected fibrations
Mauro C. Beltrametti, Tommaso de Fernex, Antonio Lanteri
Under some positivity assumptions, extension properties of rationally connected fibrations from a submanifold to its ambient variety are studied. Given a family of rational curves…
Chern Classes of the Moduli Stack of Curves
Gilberto Bini
Here we calculate the Chern classes of , the moduli stack of stable n-pointed curves. In particular, we prove that such classes lie in the tautological r…
