Vitali Vougalter, Vitaly Volpert Solvability conditions for a linearized Cahn-Hilliard equation of sixth order (125K, pdf) ABSTRACT. We obtain solvability conditions in H^6 (R^3) for a sixth order partial differential equation which is the linearized Cahn-Hilliard problem using the results derived for a Schroedinger type operator without Fredholm property in our preceding article.
