Abstract

We characterize the singularity set of massless theories by giving a complete set of the Landau polynomials. We find the general form of Gauss-Manin connection. We show that for massless theories the dependence on momenta decouples from the dependence on coupling and dimension. The latter is completely absorbed into a set of matrices that have no dependence on kinematic variables.
