Abstract:
For an arbitrary del Pezzo surface $S$, we compute $\alpha (S)$, which is the volume of a certain polytope in the dual of the effective cone of $S$, using magma and polymake. The constant $\alpha (S)$ appears in Peyre’s conjecture for the asymptotic formula for the number of rational points of bounded height on $S$ over number fields.References
