摘要 The filtration equation ut =f(u)xx has solutions which are not smooth because the diffusion coefficient has the zero point. As f’(u) is degenerate or singular a previous paper has proved the convergence of difference solutions and the existence of the solution for the differential equation. In this paper, applying a similar method in which the estimations can be improved, we study another degenerate or singular nonlinear parabolic equation
