  Resumen

  Trivalent 2-stratifolds are a generalization of 2-manifolds in that there are disjoint simple closed curves where three sheets meet. We present a classification of simply connected 2-stratifolds in terms of their associated labeled graphs. This is joint work with Jose Carlos Gomez-Larrañaga and Francisco Gonzalez-Acuña.
