| Outline of Final Research Achievements |
A holomorphic function relates a figure in the plane to a figure in the plane
without changing the angle. This is said that a holomorphic function is conformal. A holomorphic function has mathematically good properties.
If a map relates a figure in the plane to a figure in a higher dimensional space, it can be expected that the map has similarly good properties. We speculated that the best realization of this is a super-conformal map to the four dimensional Euclidean space. As a result, a super-conformal map version of a well-known theorem of a holomorphic function such as a super-conformal map version of Schwarz's lemma was proved. These properties are obtained via maps to the twistor space associated with a super-conformal map. We revealed the relation between conformal maps and the maps to the twistor space.
