Wealso show that a tropical polynomial map on the plane is an isomorphism ifall the Jacobians have the same sign (positive or negative). In addition, for atropical rational map we prove that if the Jacobians have the same sign andif its preimage is a singleton at least at one regular point then the map is anisomorphism.Lire moins >
