          Propagation of perturbations in thin capillary film equations 
          with nonlinear diffusion and convection
        We study the evolution of the support of an arbitrary strong generalized 
          solution to the Cauchy problem for the thin film equation with nonlinear 
          diffusion and convection. We find an upper bound exact (in a sense) 
          for the propagation speed of the support of this solution.
