Harmonic tori in de Sitter spaces
arXiv:1201.5696
Abstract
We show that all superconformal harmonic immersions from genus one surfaces into de Sitter spaces with globally defined harmonic sequence are of finite-type and hence result merely from solving a pair of ordinary differential equations. As an application, we prove that all Willmore tori in without umbilic points can be constructed in this simple way.
