Abstract

Let K be a compact, non-polar set in ℝm, m≥3 and let SKi(t)={Bi(s)+y: 0≤st, yK} be Wiener sausages associated to independent Brownian motions Bi, i=1, 2, 3 starting at 0. The expectation of volume of ⋂i=13SKi(t) with respect to product measure is obtained in terms of the equilibrium measure of K in the limit of large t.

Soit K un ensemble compact, non-polaire dans ℝm (m≥3) et soit SKi(t)={Bi(s)+y: 0≤st, yK} des saucisses de Wiener associées à des processus Browniens indépendants Bi, i=1, 2, 3 initalisés à 0. L’espérance des volumes de ⋂i=13SKi(t) par rapport à la mesure produit est obtenue en termes de la mesure d’équilibre de K lorsque t tend vers l’infini.
