Dr. Masaaki Umehara, is a professor of Mathematics at Tokyo Institute of Technology. In 1984 After graduating from Keio University Faculty of Engineering, Keio University Master of Science degree at the University of Tsukuba, assistant professor at the University of Tsukuba, Associate Professor at Osaka University, Professor at Hiroshima University, Professor at Osaka University and currently Professor at Tokyo Institute of Technology, Ph.D.
Research Interest
Differential geometry, Currently the maximum curved surface of the spacetime, the curved surface of the average curvature 1 of the 3 dimensional de Jitter spacetime, and the isomorphic deformation of the singular point are under investigation. In addition, we are interested in the relationship between the number of critical points and inflection points of the curvature function of the plane closed curve and the phase of the curve, and have continued research like a life work for the last 20 years.
