Abstract

This is a survey of the twistor lifts of surfaces in 4-spaces. In most part of this survey, the space is the Euclidean $4$-space $E^4$. The definitions of the Gauss maps and the twistor lifts of surfaces in $E^4$ are given by complex structures of $E^4$. Based on these definitions, we can understand that the Gauss maps of minimal surfaces are holomorphic and characterize isotropicity of minimal surfaces.
