Discrete Lorentz surfaces and s-embeddings II: maximal surfaces
Niklas Christoph Affolter, Felix Dellinger, Christian Müller +2
S-embeddings were introduced by Chelkak as a tool to study the conformal invariance of the thermodynamic limit of the Ising model. Moreover, Chelkak, Laslier and Russkikh introduce…

Constant mean curvature surfaces from ring patterns: Geometry from combinatorics
Alexander I. Bobenko, Tim Hoffmann, Nina Smeenk
We define discrete constant mean curvature (cmc) surfaces in the three-dimensional Euclidean and Lorentz spaces in terms of sphere packings with orthogonally intersecting circles.…
