Description

Let K be a convex body in Rd. Let XK be a d-dimensional random vector distributed according to the Hadwiger-Wills density μK associated with K, defined as μK(x)=ceπdist2(x,K), xRd. Finally, let the information content HK be defined as HK=dist2(XK,K).

In this talk, we will study the fluctuations of HK around its expectation as the dimension d go to infinity.
Stein's method plays a crucial role in our analysis.
This is joint work with Valentin Garino.
