Query: Exemples de comptage de courbes sur les surfaces   Let X be a surface whose Cox ring has a single relation satisfying moreover a
kind of linearity property. Under a simple assumption, we show that the
geometric Manin's conjectures hold for some degrees lying in the dual of the
effective cone of X (in particular, for those degrees the moduli space of
morphisms has the expected dimension). The result applies to a class of
generalized del Pezzo surfaces which has been intensively studied in the
context of the arithmetic Manin's conjecture.
