GRAPHS ASSOCIATED TO FOLD MAPS FROM CLOSED SURFACES TO THE PROJECTIVE PLANE.
- Authors

- Abstract
We describe in this paper how to attach a weighted graph to any fold map (i.e., a stable map without cusps) with planar apparent contour from a closed surface to the projective plane. Also we study necessary and sufficient conditions for a weighted graph with non negatively weighted vertices to be the graph of a fold map from a closed surface to the projective plane.
