abstract
We provide an existence proof for two 1-parameter families of embedded triply periodic minimal surfaces of genus three, namely the tG family with tetragonal symmetry that contains the gyroid, and the rGL family with rhombohedral symmetry that contains the gyroid and the Lidinoid, both discovered numerically in the 1990s. The existence was previously proved within a neighborhood of the gyroid and the Lidinoid, using Weierstrass data defined on branched rectangular tori. Our main contribution is to extend the technique to branched tori that are not necessarily rectangular.

Stacking disorder in periodic minimal surfaces
Balanced, non-degenerate node configurations on a flat torus produce 1-parameter families of embedded, non-periodic minimal surfaces of infinite genus, with prescribed stacking disorder.
