Unirationality of Certain Universal Families of Cubic Fourfolds,ational over the Hassett divisors ., in the range 8 ≤ d ≤ 42. By applying inductively this argument, we are able to show that, in the same range of values, . is unirational for all integer values of .. Finally, we observe that for explicit infinitely many values of ., the universal cubic fourfold ov

Supersingular Irreducible Symplectic Varieties,lizations of K3 surfaces. We propose to study such varieties defined over fields of positive characteristic, especially the supersingular ones, generalizing the theory of supersingular K3 surfaces..In this work, we are mainly interested in the following two types of symplectic varieties over an alge

A Refinement of the Motivic Volume, and Specialization of Birational Types, of the motivic volume and its birational version introduced by Kontsevich and Tschinkel to prove the specialization of birational types. We also provide several explicit examples of obstructions to stable rationality arising from this technique.
