Two spectral sequences are defined respectively for cohomologies H-p(Omega(f,k-.,0)(.)) and H-p(Lambda(f,k-.,0)(.)) of singularities of C-infinity mappings. They are finitely dimensional new invariances under right equivalences and contact transformations respectively. Formulae to be computed by linear algebra are proved.
