对于分割光滑Del Pezzo曲面,我们分析了有效锥体的结构,并证明了$\alpha$值的递归公式,出现在马宁佩尔猜想关于曲面上有界高度有理点数量的预测的前导常数中。此外,我们计算 $\ge 3$ 度的所有奇异 Del Pezzo 曲面的 $\alpha$。
For split smooth Del Pezzo surfaces, we analyse the structure of the effective cone and prove a recursive formula for the value of $\alpha$, appearing in the leading constant as predicted by Peyre of Manin's conjecture on the number of rational points of bounded height on the surface. Furthermore, we calculate $\alpha$ for all singular Del Pezzo surfaces of degree $\ge 3$.
