Abstract
In this talk, we will discuss the behavior of birational automorphism groups of projective hyper-Kähler manifolds. We will see that these groups are "semicontinuous" in families and, for nontrivial families of hyper-Kähler manifolds of the known deformation types, the locus of manifolds with infinite birational automorphism groups is dense. This is joint work with Francesco Denisi, Claudio Onorati, and Francesca Rizzo.
