摘要

我们研究了雅各布具有非难 p 扭转的度量矩阵的比例。我们在这些雅各布与配置超曲面上的 Fp 有理点之间建立了对应关系，从而将它们的比例联系起来。通过计算有限域上的点，我们证明这些雅各布的比例在渐近上等同于 1/p。

On the proportion of metric matroids whose Jacobians have nontrivial p-torsion

We study the proportion of metric matroids whose Jacobians have nontrivial p-torsion. We establish a correspondence between these Jacobians and the $F_{p}$ -rational points on configuration hypersurfaces, thereby relating their proportions. By counting points over finite fields, we prove that the proportion of these Jacobians is asymptotically equivalent to $1 / p$ .
