Let \(p\) be the principal symbol of a hyperbolic (pseudo) differential operator of order \(m\) admitting at most double characteristic roots. Suppose that at each point \(\rho\) of the double characteristic manifold \(\Sigma\) of \(p\) the Hamiltonian matrix of \(p, F_{p}\), has a Jordan block of d
