We perform a systematic study of the image of the Gauss map for complete minimal surfaces in Euclidean four-space. In particular, we give a geometric interpretation of the maximal number of exceptional values of the Gauss map of a complete orienta...

For a minimal surface in the Euclidean 4-space, a semiumbilic point is at which its normal curvature vanishes. We prove that the semiumbilic points are isolated, if the normal curvature neither changes its sign nor vanishes identically. We also sh...
