denote une lamination (compacte, nonsingulière) par surfaces de Riemann hyperboliques. On montre qu’ une mesure sur est harmonique si et seulement si elle est la projection d’une mesure sur le fibré tangent unitaire qui est invariante sous les flots géodesique et horocyclique.
denotes a (compact, nonsingular) lamination by hyperbolic Riemann surfaces. We prove that a probability measure on is harmonic if and only if it is the projection of a measure on the unit tangent bundle of which is invariant under both the geodesic and the horocycle flows.
Mots clés : foliated spaces, harmonic measures, brownian motion on the hyperbolic plane, geodesic flow, horocycle flow
