Rational curves on O'Grady's tenfolds
Thanks to some recent works due to F. Charles, G. Mongardi and G. Pacienza, we know that, in order to show the existence of rational curves on irreducible holomorphic symplectic (IHS) varieties of a fixed deformation type, it is enough to do it for special points of their moduli space, thanks to the study of the monodromy group of the variety. In this talk I will start introducing the problem of finding rational curves on IHS varieties and presenting some motivation behind it; I will describe the state of the art of the problem and I will present my contribution to the OG10-case, giving examples of ample uniruled divisors on OG10-varieties.

Hodge structures of K3 type in Fano varieties
Subvarieties of Grassmannians (and especially Fano varieties) obtained from section of homogeneous vector bundles are far from being classified. A case of particular interest is given by the Fano varieties of K3 type (FK3), for their deep links with hyperkähler geometry. In this talk we will present some examples of recently discovered FK3 varieties, and a general procedure that allows us to spread a (Hodge) K3 structure as a component of the Hodge structure of different varieties. This is in collaboration with Giovanni Mongardi and Marcello Bernardara--Laurent Manivel.

On compact hyperkähler orbifolds
Since Bogomolov's decomposition theorem, hyperkähler manifolds play an important role in algebraic geometry; they can be considered as elementary bricks for classifying kähler manifolds with trivial first Chern class. However, in the framework of the minimal model program, we remark that considering only smooth varieties is not enough to provide a satisfactory classification. Hyperkähler orbifolds partially answer to this problem. An orbifold is a generalization of a manifold obtained by gluing quotients of open sets of C^n by finite groups. In this talk, I will give an overview of the recent progress in this area and sketch a classification of the known examples.
