Abstract/Media

A Fano variety is said to be birationally superrigid if  every birational map from it to a Mori fiber space is an isomorphism. In this talk, we investigate whether these exists a nice moduli for this very special class of Fano varieties. Such moduli would exist if birational superrigidity is a locally closed property in family. We show that this is not true in general by providing a counterexample.
