Structure of nonlinear PDEs of elliptic and parabolic type
Current  research 

It is well known that nonlinear PDEs of elliptic and parabolic type can describe various phenomena arising in natural and social science. It is also known that there are many PDEs exhibiting interesting phenomena in a pure mathematical viewpoint. I am interested in the number of the solutions of those PDEs and properties of each solution including the shape and the Morse index.
