Isotropy of 6-dimensional quadratic forms over function fields of quadrics, by Oleg Izhboldin and Nikita Karpenko

Let phi be an anisotropic 6-dimensional quadratic form over a field of characteristic different from 2. We study the last open cases in the problem of describing the quadratic forms psi such that phi becomes isotropic over the function field of psi.
