Resumen de A topological characterization of the ?-limit sets for analytic flows on the plane, the sphere and the projective plane

Víctor Jiménez López, Jaume Llibre

• In this paper the ?-limit sets for analytic and polynomial differential equations on the plane are characterized up to homeomorphisms. The analogous problem is solved in full detail for analytic flows on the sphere and the projective plane. We also explain how to carry on the same program for analytic flows defined on open subsets of these surfaces.
