On construit une nouvelle théorie de Hodge sur le fibré cotangent d’une variété Riemannienne . Le Laplacien correspondant est un opérateur hypoelliptique d’ordre deux, qui est autoadjoint relativement à une forme Hermitienne de signature . Cette théorie de Hodge interpole entre la théorie de Hodge habituelle sur et le flot géodésique sur .
We construct a new Hodge theory on the cotangent bundle of a Riemannian manifold . The corresponding Laplacian is a second order hypoelliptic operator, which is self-adjoint with respect to a Hermitian form whose signature is . This Hodge theory interpolates between the classical Hodge theory on and the geodesic flow on .
