Abstract.We give a new proof of the existence of the Green Bundles.
Let (M, g) be a compact Riemannian manifold, denote by gtits geodesic flow on
the tangent bundle T M. Let ss : T M ! M be the canonical projection and for all
` 2 T M let V (`) be the kernel of dss`. Two points `1, `2 are said to be conju*
