| Abstract : | A model for phase separation in multicomponent systems is studied. In particular the possibility of a concentration dependence of the mobility matrix is taken into account. This leads to a system of fourth order degenerate parabolic partial differential equations. We derive these equations from balance laws, show some properties of the model and prove a global existence result for the degenerate system., |
