Universal unramified cohomology of cubic fourfolds containing a plane
arXiv:1310.6705
Abstract
We prove the universal triviality of the third unramified cohomology group of a very general complex cubic fourfold containing a plane. The proof uses results on the unramified cohomology of quadrics due to Kahn, Rost, and Sujatha.
