Research Interests: PDE, Calculus of Variation, Control Theory, Material Science

My research interest is the mathematical analysis of nonlinear evolution equations derived from physics problems, especially in materials science and surface science. I mainly work on 4th order degenerated parabolic equations, coupled equations with dynamic boundary condition and multiscale problems. The methods invovled are entropy method, calculus of variation, gradient flows, numerical simulation, operator theory, and control theory.

Keywords:

Diffusion processes and stochastic analysis on manifolds • Dimension reduction (Statistics) • General behavior of solutions of PDE (comparison theorems; oscillation, zeros and growth of solutions; mean value theorems) • PDE in connection with control problems • PDE with multivalued right-hand sides • Simulation and numerical modeling
