Exploding the Wente Torus

Constant mean curvature torus and cylinders in euclidean 3-space

This sequence of images shows what happens when one of the periods of a Wente torus is broken: the surface explodes into a periodic bubbleton. The sequence was constructed by following a flow [2] through spectral genus 2 CMC cylinders, starting at a round cylinder. Two double points on the spectal curve were opened up to become branch points of the genus 2 spectal curve.

The three-lobed Wente torus before being exploded.
One period is broken; the surface instantly becomes a cylinder.
The surface, which extends infinitely in both directions, is shown here cut off at both ends.
The bubbles separate.
A 3-lobed periodic bubbleton. The continued flow increases the distance between the bubbles to infinity.
