Rational points on conic bundle surfaces via additive combinatorics (30')
speaker: Tim Browning (Bristol University)abstract: Methods of Green and Tao can be used to prove the Hasse principle and weak approximation for some special intersections of quadrics defined over the rational numbers. This implies that the Brauer-Manin obstruction controls weak approximation on conic bundles with an arbitrary number of degenerate fibres, all defined over the rationals. This is joint work with Lilian Matthiesen and Alexei Skorobogatov
