Rational points on complete intersections of cubic and quadric hypersurfaces over Fq(t) Using a two-dimensional version of the delta method, we establish an asymptotic formula for the number of rational points of bounded height on non-singular complete intersections of cubic and quadric hypersurfaces of dimension at least 23 over Fq(t), provided char (Fq)>3. Under the same hypotheses, we also verify weak approximation. 110 4 London Mathematical Society application/pdf
