Research Summary : I am studying the Schröodinger equation on noncompact manifolds. The research of the Schröodinger equation on the Euclidean space has a long history, and lots of powerful tools and techniques have been developped in order to treat a wide variety of perturbations. I believe that such powerful theories should be applicable to more geometric problems too, and would provide new methods or theories in the geometric analysis.
