The existence of such curves with prescribed topological data has a lot of geometric restrictions. We show how to use the theory of singular complex analytic spaces to obtain such restrictions. We also study topological properties of such arrangementsengbook parthttp://cisne.sim.ucm.es/record=b2133599~S6*spiopen access512.772CurvesGeometria algebraica1201.01 Geometría Algebraica
