Research Themes
Value-distribution-theoretic properties for Gauss maps of various classes of surfaces
Our aim of this study is to elucidate global behavior of Gauss maps of immersed surfaces in space-forms, for example, minimal surfaces and constant mean curvature (CMC, for short) surfaces in Euclidean space, flat surfaces in hyperbolic three-space.
Studies on Bernstein-type theorems for immersed surfaces
We plan to obtain Bernstein type theorems and Weierstrass type representations for immersed surfaces.
