A note on the box dimension of degenerate foci

Dynamical Systems 2017-05-02 v1

Abstract

We study polynomial planar systems with singularity of focus type without characteristic directions. Simple and natural transformation of weak focus has been used to obtain such degenerate focus. We compute the box dimension of a spiral trajectory, and show connection to cyclicity of the system under a perturbation.
