The Asymptotic Behavior of the Solutions of Degenerate Parabolic Equations

Existence of stationary states is established by means of the method of upper and lower solutions. The structure of the solution set is discussed and a uniqueness property for certain classes is proved by a generalized maximum principle. It is then shown that all solutions of the parabolic equation converge to a stationary state.

Asymptotic expansions for degenerate parabolic equations

Article history: Received 14 May 2014 Accepted after revision 26 September 2014 Available online 11 October 2014 Presented by Olivier Pironneau We prove asymptotic convergence results for some analytical expansions of solutions to degenerate PDEs with applications to financial mathematics. In particular, we combine short-time and global-in-space error estimates, previously obtained in the unifo...

Time Resealing and Asymptotic of Some Fourth-Order Behavior Degenerate Diffusion Equations

Abstract-In this paper, we investigate the large-times behavior of weak solutions to the fourthorder degenerate parabolic equation ut = -(I@ ~~~~~~ modeling the evolution of thin films. In particular, for all n > 0, we prove exponential decay of u(z, t) towards its mean value (l/If20 Jn u dz in L1-norm for long times and we give the explicit (n-dependent) rate of decay. The result is baaed on c...
