Abstract
We consider weak entropy measure-valued soluti ons of the Neumann initial-boundary value problem for the equation ut = [ø(u)]xx, where ø is nonmonotone. These solutions are obtained from the corresponding problem for the regularized equation ut = [ø(u)]xx + euxxt (∈ > 0) by a vanishing viscosity method and satisfy a family of suitable entropy inequalities. Relying on a strong version of these inequalities, we prove exhaustive results concerning the long-time behavior of solutions. © 2010 Societ y for Industrial and Applied Mathematics.File | Dimensione | Formato | |
