| Outline of Final Research Achievements |
We elucidated the geometric background of function-theoretic properties for the Gauss maps of several classes of immersed surfaces in three-dimensional space forms, for example, minimal surfaces in Euclidean three-space, improper affine spheres in the affine three-space and flat surfaces in hyperbolic three-space. In particular, we give an effective curvature bound for a specified conformal metric on an open Riemann surface. As an application of the result, we revealed the geometric meaning of the maximal number of exceptional values of Gauss maps for these surfaces.
