Periodic Steiner networks minimizing length

Differential Geometry 2018-04-26 v2 Combinatorics

Abstract

We study a problem of geometric graph theory: We determine the triply periodic graph in Euclidean 3-space which minimizes length among all graphs spanning a fundamental domain of 3-space with the same volume. The minimizer is the so-called srs network with quotient the complete graph on four vertices K4K_4. The network spans the body centred cubic lattice and is related to the gyroid triply periodic surface.
