We introduce Möbius invariant objects - discrete holomorphic quadratic differentials to connect discrete complex analysis, discrete integrable systems and geometric rigidity. Discrete holomorphic quadratic differentials parametrize the change of the logarithmic cross ratios of planar discrete surfaces under infinitesimal conformal deformations. We show that on planar triangulated disks, there is a one-to-one correspondence between discrete holomorphic quadratic differentials and discrete harmonic functions modulo linear functions. Furthermore, every discrete holomorphic quadratic differential yields an S 1-family of discrete minimal surfaces via a Weierstrass representation. It leads to a unified theory of discrete minimal surfaces, establi...
