Manin's conjecture for spherical Fano threefolds

-
Ulrich Derenthal, IAS and Leibniz Universit盲t Hannover

When an algebraic variety over the rational numbers contains infinitely many rational points, we may study their distribution. In particular, for Fano varieties, the asymptotic behavior of the number of rational points of bounded height is predicted by Manin鈥檚 conjecture.

In this talk, we discuss a proof of Manin鈥檚 conjecture for smooth spherical Fano threefolds. In one case, in order to obtain the expected asymptotic formula, it is necessary to exclude a thin subset with exceptionally many rational points from the count. This is joint work with V. Blomer, J. Br眉dern and G. Gagliardi.
