Abstract
AbstractWe show that the homogeneous and the 2-lobe Delaunay tori in the 3-sphere provide the only isothermic constrained Willmore tori in 3-space with Willmore energy below $$8\pi $$
8
π
. In particular, every constrained Willmore torus with Willmore energy below $$8\pi $$
8
π
and non-rectangular conformal class is non-degenerated.
