This control problem regards the viscous Cahn-Hilliard equation with possibly singular potentials and dynamic boundary conditions.application/pdfeng510Cahn-Hilliard equationdynamic boundary conditionsphase separationsingular potentialsoptimal controlfirst and second order optimality conditionsadjoint state systemReport
