Phase portraits of Abel quadratic differential systems of second kind with symmetries

Abstract

Altres ajuts: Universitat Jaume I grant P1-1B2015-16

We provide normal forms and the global phase portraits on the Poincaré disk of the Abel quadratic differential equations of the second kind having a symmetry with respect to an axis or to the origin. Moreover, we also provide the bifurcation diagrams for these global phase portraits.
