Recently Graber, Harris and Starr proved that any family of rationally connected projective varieties over a smooth curve has a section. A complex projective variety (or manifold) M is rationally connected when every two points in M lie on a rational curve in M. We will explain a generalization of this result, joint with Jason Starr, to the case when the base of the family is a surface. We will mention the analogy with Tsen’s theorem and the connection with the period-index problem for Brauer groups.
