Harmonic tori in de Sitter spaces \(S ^ {2n}_1\)

Emma Carberry and Katharine Turner

Abstract

We show that all superconformal harmonic immersions from genus one surfaces into de Sitter spaces \(S^{2n}_1\) 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 \(S^3\) without umbilic points can be constructed in this simple way.
