Graphs of stable maps from closed orientable surfaces to the 2-sphere
Autor/es: Derek Hacon, Catarina Mendes de Jesus, Mª Carmen Romero Fuster
We prove that any bipartite weighted graph with non negatively weighted vertices is the graph of some stable map from a closed orientable surface to the sphere and obtain necessary and sufficient conditions on a graph to be the graph of a fold map of prefixed degree.
