We prove that if M is a closed surface and V is a divergence-free C-vector field with finitely many singularities on M then every orbit L of V is one of the following types: (i) a singular point, (ii) a periodic orbit, (iii) a closed (non periodic) orbit in M∗ = M − Sing(V), (iv) a locally dense orbit, where Sing(V) denotes the set of singular points of V . On the other hand, we show that the complementary in M of periodic components and minimal components is a compact invariant subset consisting of singularities and closed (non compact) orbits in M∗. These results extend those of T. Ma and S. Wang in [Discrete Contin. Dynam. Systems, 7 (2001), 431–445] established when the divergence-free vector field V is regular that is all its singular points are non-degenerate. 2010 Mathematics Subject Classification.

Not the same thing can be said about m-Möbius transformations m f mapping m  onto  . Even for the simplest entity, the pre-image by m f of a unique point, there is no way of visualization. Pre-images by m f of figures from  are like ghost figures in m  . This paper is about handling those ghost figures. We succeeded in doing it and proving theorems about them by using their projections onto the coordinate planes. The most im-portant achievement is the proof in that context of a theorem similar to the symmetry principle for Möbius transformations. It is like saying that the images by m-Möbius transformations of symmetric ghost points with respect to ghost circles are symmetric points with respect to the image circles. Vectors in m  are well known and vector calculus in m  is familiar, yet the pre-image by m f of a vector from  is a different entity which materializes by projections into vectors in the coordinate planes. In this paper, we study the interface between those entities and the vectors in m  .
