“Fano varieties with torsion in the third cohomology group”
Abstract: I will explain a construction of Fano varieties with torsion in their third cohomology group. The examples are constructed as double covers of linear sections of rank loci of symmetric matrices, and can be seen as higher-dimensional analogues of the Artin– Mumford threefold. As an application, we will answer a question of Voisin on the coniveau and strong coniveau filtrations of rationally connected varieties.
