We give a dimension bound on the irreducible components of the characteristic variety of a system of linear partial di erential equations deΓΏned from a suitable ΓΏltration of the Weyl algebra An. This generalizes an important consequence of the fact that a characteristic variety deΓΏned from the order
For a Riemannian foliation F on a compact manifold M with a bundle-like metric, the de Rham complex of M is C-splitted as the direct sum of the basic complex and its orthogonal complement. Then the basic component cb of the mean curvature form of F is closed and defines a class (Y) in the basic coho
