The dynamics of nucleation for the Cahn-Hilliard equation. (English) Zbl 0788.35061

The authors show a description of the dynamics of nucleation for the Cahn-Hilliard equation in one space dimension, discussing some of the fundamental mathematical issues related to this important event. They carry out their study in the case of an initial boundary value problem in one space dimension on a finite interval, assuming the equation of the form \[ {\partial u \over \partial t}={\partial^ 2 \over \partial x^ 2} \left(-\varepsilon^ 2 {\partial^ 2 \over \partial x^ 2} u+f(u) \right) \] with Neumann boundary conditions \((\partial u/ \partial x=\partial^ 3 u/ \partial x^ 3=0)\) at the endpoints of the interval.
