Malte Hassler

AI总结:

研究平面首达渗流中通过时间的非随机波动,证明在某些条件下波动至少为$\sqrt{\log n}$量级,改进了Nakajima的$\log(\log(n))$界,并首次证明任意方向波动的发散性。

摘要:

首达渗流中通过时间的波动备受关注。我们证明,在已知对一大类绝对连续边权分布成立的一些条件下,平面FPP中的非随机波动至少为$\sqrt{\log n}$量级。这改进了Nakajima证明的$\log(\log(n))$界,并且是首次显示任意方向波动发散的结果。我们的证明应用了Dembin、Elboim和Peled关于BKS中点问题的最新工作以及Mermin-Wagner型估计的发展。

英文摘要:

The fluctuations of the passage time in first passage percolation are of great interest. We show that the non-random fluctuations in planar FPP are at least of order $\sqrt{\log n}$ under some conditions that are known to be met for a large class of absolutely continuous edge weight distributions. This improves the ${\log(\log(n))}$ bound proven by Nakajima and is the first result showing divergence of the fluctuations for arbitrary directions. Our proof is an application of recent work by Dembin, Elboim and Peled on the BKS midpoint problem and the development of Mermin-Wagner type estimates.
