摘要:
我们证明,面积等于亏格的 Masur-Smillie-Veech(MSV)分布随机平移曲面序列,在亏格趋于无穷时发生 Benjamini-Schramm 收敛。这意味着,对任意固定半径 $r>0$,若 $X_g$ 是面积为 $g$、亏格为 $g$ 的 MSV 分布随机平移曲面,且 $o$ 是 $X_g$ 中均匀随机选取的点,则 $X_g$ 中 $o$ 的半径 $r$ 邻域作为带点测度度量空间,依分布收敛于 Poisson 平移平面中根的半径 $r$ 邻域;Poisson 平移平面是我们在此引入的随机带点曲面。在此过程中,我们还得到了平移曲面统计局部几何性质的界,例如随机点 $o$ 的单射半径至多为 $r$ 的概率,这些结果本身可能具有独立意义。
英文摘要:
We prove that the sequence of Masur-Smillie-Veech (MSV) distributed random translation surfaces, with area equal to genus, Benjamini-Schramm converges as genus tends to infinity. This means that for any fixed radius $r>0$, if $X_g$ is an MSV-distributed random translation surface with area $g$ and genus $g$, and $o$ is a uniformly random point in $X_g$, then the radius-$r$ neighborhood of $o$ in $X_g$, as a pointed measured metric space, converges in distribution to the radius $r$ neighborhood of the root in a Poisson translation plane, which is a random pointed surface we introduce here. Along the way, we obtain bounds on statistical local geometric properties of translation surfaces, such as the probability that the random point $o$ has injectivity radius at most $r$, which may be of independent interest.
