Volumetric properties of the convex hull of an \(n\)-dimensional Brownian motion. (English) Zbl 1298.52005

The object of this paper is to study the convex hull \(K\) of the standard Brownian motion in \(\mathbb R^n\). The author extends some known results from the planar case to the higher dimensional case, as well as obtains certain asymptotics of the behaviour of these objects as the dimension goes to infinity. He introduces new methods which may be further used to study volumetric and combinatorial properties of the convex hull of the Brownian motion and random walk.
