Abstract

For d2d \geq 2 let BB be standard dd-dimensional Brownian motion. For any α<1/d\alpha < 1/d we construct an α\alpha-H\"{o}lder continuous function f ⁣:[0,1]Rdf \colon [0,1] \to \mathbb{R}^d so that the range of BfB-f covers an open set. This strengthens a result of Graversen (1982) and answers a question of Le Gall (1988).
