Vertical Brauer groups and del Pezzo surfaces of degree 4

Anthony Várilly-Alvarado, Bianca Viray

We show that Brauer classes of a locally solvable degree 4 del Pezzo surface X are vertical for some projection away from a plane f: X ---> P^1, i.e., that every Brauer class is ob…

Cubic fourfolds containing a plane and a quintic del Pezzo surface

Asher Auel, Marcello Bernardara, Michele Bolognesi +1

We isolate a class of smooth rational cubic fourfolds X containing a plane whose associated quadric surface bundle does not have a rational section. This is equivalent to the nontr…
