Abstract:
There has been recently an important interest in deriving rigorously the Cahn-Hilliard equation from the nonlocal equation. Since we are motivated by models for the biomechanics of living tissues, it is useful to include degenerate motilities. In this framework, we present a method to show the convergence of the nonlocal to the local degenerate Cahn-Hilliard equation. The method includes the use of nonlocal Poincare and compactness inequalities.
