Partial Differential Equations and Harmonic Analysis


 I have been working on the mathematical theories of degenerate and singular elliptic or parabolic partial differential equations and the free boundary problems. This study includes the existence, uniqueness, regularity and symmetric properties of a solution of a partial differential equation or a free boundary problem. These problems originate in physics and engineering and have seen application in science, engineering and economics.
