Every smooth foliation
of a manifold V gives rise very naturally to a von Neumann algebra
. The weights on M correspond exactly to operator valued forms on the “manifold” of leaves of
. We compute their modular automorphism group, this yields the continuous decomposition of M in terms of another foliation
of V and a one parameter group of automorphisms of
. We then illustrate this decomposition with a few examples.
