On Twistor Gauss Maps of Surfaces in 4-Spheres

On Twistor Gauss Maps of Surfaces in 4-Spheres

<正> In this paper we study surfaces in S~4 and their twistor Gauss maps.Some necessaryand sufficient conditions that the twistor Gauss map is harmonic are given.We find many examplesof nonisotropic harmonic maps from a surface to(?)P~3.
