On the expected diameter of planar Brownian motion

James McRedmond, Chang Xu

Known results show that the diameter $d_{1}$ of the trace of planar Brownian motion run for unit time satisfies $1.595 \leq E d_{1} \leq 2.507$ . This note improves these bound…

Convex hulls of planar random walks

Chang Xu

For the perimeter length $L_{n}$ and the area $A_{n}$ of the convex hull of the first $n$ steps of a planar random walk, this thesis study $n \to \infty$ mean and variance asymptotics…
