ABSTRACT
The aim of this paper is to study the couple of stable plane Gauss maps from a global point of view, where M is a smooth closed orientable surface, f 2 is a projection and f 3 is Gauss map. We associate this maps a pair of ℳℱ-graph. We will study their properties, giving conditions on the graphs that can be realized by pairs of maps with couples from pre-determined singular sets.
