Staff Introduction
I have researched various problems with continuous variables such as variational problems,
nonlinear programming problems, and best approximation problems, by using functional
analysis. My current research interests lie in the continuous and discrete structure of
optimization and game theory. For instance, discretization of time variable in variational
problems reach extremal problems in a finite dimension space. It has been clarified that the
conjugate point theory for variational problems can be developed for extremal problems. I am
also esearching discrete fixed point theorem and its application to the game theory. I research
a duality theory in optimization. I work on origami mathematics. The main themes are the
orizuru deformation theory and the flat foldability. Furthermore, I wantto challenge wide fields
in the future.
Keywords  Optimization Theory, Fixed Point Theorem, Game Theory, Origami Math.
