Outline of Final Research Achievements

We introduced a new method for the study of parabolic concavity properties of solutions to parabolic boundary value problems and proved that a solutions of a nonlinear parabolic equation has parabolic power concavity properties. Furthermore, applying the arguments to parabolic concavity properties, we obtained parabolic power concavities of solutions to nonlinear parabolic systems and the relationship among the Minkowski additions of domains and the solutions of parabolic boundary value problems.
