Separatrix Configurations of Quadratic Systems with Finite Multiplicity Three anda M(sup 0)1,1 Type of Critical Point at Infinity

摘要

This paper is one in a series on the classification of phase portraits ofquadratic systems. In it, the classifcation of separatix configuration is investigated for quadratic systems with finite multiplicity three and an infinite saddle node M sub 1,1, superscript 0, and 188 topologically different separatix configurations are obtained.
