平面布朗运动沿其轨迹均匀缠绕

Planar Brownian motion winds evenly along its trajectory

Isao Sauzedde

摘要:

设$D_N$为平面布朗运动至少绕其旋转$N$次的点的集合。证明了当$N$趋于无穷大时,密度为$2 πN 1_{D_N}$的平面上的随机测度关于勒贝格测度几乎必然弱收敛于布朗运动的占有测度.

英文摘要:

Let $D_N$ be the set of points around which a planar Brownian motion winds at least $N$ times. We prove that the random measure on the plane with density $2 πN 1_{D_N}$ with respect to the Lebesgue measure converges almost surely weakly, as $N$ tends to infinity, towards the occupation measure of the Brownian motion.
