DESCRIPTION:Ulrich Derenthal (Leibniz Universität Hannover)\nManin's conj
 ecture predicts the asymptotic behavior of the number of rational points o
 f bounded height on Fano varieties over number fields. We prove this conje
 cture for a family of nonsplit singular quartic del Pezzo surfaces over th
 e rationals. The proof uses a nonuniversal torsor. This is joint work in p
 rogress with Marta Pieropan.
