Tightness for Thick Points in two dimensions

preprint2022arXivOpen access

Abstract

Let WtW_{t} be Brownian motion in the plane started at the origin and let θ θ be the first exit time of the unit disk D1D_{1}. Let μθ(x,ε)=1πε2∫0θ1{B(x,ε)}(Wt) dt,μ_{ θ} ( x,ε) =\frac{1}{πε^{ 2} }\int_{0}^{ θ}1_{\{ B( x,ε)\}}( W_{t})\,dt, and set μθ∗(ε)=sup⁡x∈D1μθ(x,ε)μ^{ \ast}_{ θ} (ε)=\sup_{x\in D_{1}}μ_{ θ} ( x,ε). We show that μθ∗(ε)−2/π(log⁡ε−1−12log⁡log⁡ε−1)\sqrt{μ^{\ast}_θ (ε)}-\sqrt{2/π} \left(\log ε^{-1}- \frac{1}{2}\log\log ε^{-1}\right) is tight.
