Resumen de Nondegenerate linearizable centres of complex planar quadratic and symmetric cubic systems in C2

C. Rousseau, Colin Christopher

  • In this paper we consider complex differential systems in the plane, which are linearizable in the neighborhood of a nondegenerate centre. We find necessary and sufficient conditions for linearizability for the class of complex quadratic systems and for the class of complex cubic systems symmetric with respect to a centre.

    The sufficiency of these conditions is shown by exhibiting explicitly a linearizing change of coordinates, either of Darboux type or a generalization of it.
