Abstract

We study the limiting shape of the connected components of the vacant set of two-dimensional Brownian random interlacements: we prove that the connected component around xx is close in distribution to a rescaled \emph{Brownian amoeba} in the regime when the distance from xCx\in\mathbb{C} to the closest trajectory is small (which, in particular, includes the cases xx\to\infty with fixed intensity parameter α\alpha, and α\alpha\to\infty with fixed xx). We also obtain a new family of martingales built on the conditioned Brownian motion, which may be of independent interest.
