Regular minimal nets on surfaces of constant negative curvature

Abstract

An embedded cubic graph consisting of segments of geodesics such that the angles at any vertex are equal to $2\pi/3$ is a closed local minimal net. This net is regular if all segments of geodesics are equal. The problem of classification of closed local minimal nets on surfaces of constant negative curvature has been formulated in the context of the famous Plateau problem in the one-dimensional case. In this paper we prove an asymptotic for $\sharp (W^r(g))$ as $g\to +\infty$ where $g$ is genus and $W^r(g)$ is the set of the regular single-face minimal nets on surfaces of curvature -1. Then we construct some examples of $f$-face regular nets, $f>1$.
