Sumario:[EN] The singularities of a stable Gauss map of a closed orientable surface immersed generically in three-dimensional Euclidean space, according to H. Whitney¿s Theorem, are of the fold and cusp types. The singular set of a stable Gauss map of a surface, which consists of curves of fold points containing isolated cusp points, is the parabolic set on the surface. Each parabolic curve of the singular set separates a hyperbolic region from an elliptic region of the surface. In this work, we will explore how weighted graphs can be associated with stable Gauss maps and present a general result that determines necessary and sufficient conditions for a weighted graph to be associated with a stable Gauss map.
