Summary

Introduction

15(2016), 327–348] all first integrals and phase portraits were constructed for the family of cubic differential systems with the maximum number of invariant straight lines, i.e. 9 (considered with their multiplicities). In Theorem 3.1 we describe all the 51 possible configurations of invariant lines which could possess the cubic systems in the class CSL8.
