Let be the -valued process with independent Bessel components and with indices p and q strictly positive. In this paper we compute explicitly the law of the hitting time and place of a circle, centered at the origin, when starts from the center and deduce a Reuter-type independence result. We use mainly analytical tools from PDE theory.
Soit le processus dans ayant deux composantes de Bessel indépendantes et d'indices, respectivement, p et q strictement positifs. Dans cet article, nous trouvons explicitement la loi du temps et place de sortie d'un cercle, centré à l'origine, quand démarre du centre et on déduit un théorème d'indépendance apparenté à celui de Reuter. On utilise principalement des outils analytiques de la théorie des EDP.
