Isaac García Rodríguez , Maite Grau Montaña , Jaume Giné Mesa

• Abstract In this paper we give a very easy to compute necessary condition in the monodromy problem for all singular point of analytic differential systems in the real plane. Our main tool is considering the analytic function, angular speed, and studying its limit through straight lines to the singular point.
