Weak Solutions for a Fourth Order Degenerate Parabolic Equation

Changchun Liu, Jinyong Guo (2006)

Bulletin of the Polish Academy of Sciences. Mathematics

Similarity:

We consider an initial-boundary value problem for a fourth order degenerate parabolic equation. Under some assumptions on the initial value, we establish the existence of weak solutions by the discrete-time method. The asymptotic behavior and the finite speed of propagation of perturbations of solutions are also discussed.
