我们针对有限域$\boldsymbol{\frak{M}}_g(\boldsymbol{\frak{F}}_q)$中曲线的平均类数增长率提出一种启发式方法。该启发式基于通用雅可比的稳定上同调主导迹公式点计数的假设,遵循Achter等人的方法,证明其意味着此类曲线的ζ函数零点随亏格$g\to\boldsymbol{\frak{M}}_g(\boldsymbol{\frak{F}}_q)$趋于无穷时在圆上等分布。

英文摘要

We propose a heuristic for the growth rate of the average class number of curves in $\mathcal M_g(\mathbb F_q)$ as $g \to \infty$. We show that this heuristic implies that the zeros of the zeta functions of such curves become equidistributed on the circle as $g\to\infty$. Our heuristic is based on the assumption that the stable cohomology of the universal Jacobian dominates a point count using the trace formula, following the method of Achter et al.
