Automorphisms of hypersurfaces in polarized varieties
Ana Quedo
Let be a projective variety, let be a normally generated line bundle on , and let be a general projective variety. We establish a uniform criterio…

Geometric realizations of non-symplectic involutions on the Hilbert square of a K3 surface
Ana Quedo
We give new examples of geometric constructions of non-natural non-symplectic involutions of IHS manifolds whose existence is guaranteed by previous results of Bossière-Cattaneo-Ni…

The Kawamata-Morrison Cone Conjecture for Generalized Hyperelliptic Variety
Martina Monti, Ana Quedo
A Generalized Hyperelliptic Variety (GHV) is the quotient of an abelian variety by a free action of a finite group which does not contain any translation. These varieties are natur…

Automorphisms of quartic surfaces and Cremona transformations
Daniela Paiva, Ana Quedo
In this paper, we consider the problem of determining which automorphisms of a smooth quartic surface are induced by a Cremona transformation of $\mathbb{P…
