Transforms for minimal surfaces in the 5-sphere
J. Bolton, L. Vrancken
We define two transforms between minimal surfaces with non-circular ellipse of curvature in the 5-sphere, and show how this enables us to construct, from one such surface, a sequen…

Parallel surfaces in affine 4-space
C. Scharlach, L. Vrancken
We study affine immersions as introduced by Nomizu and Pinkall. We classify those affine immersions of a surface in 4-space which are degenerate and have vanishing cubic form (i.e.…
