First integrals and phase portraits of planar polynomial differential cubic systems with invariant straight lines of total multiplicity eight

Electronic Journal of Qualitative Theory of Differential Equations, 2017
Summary: In the article [\textit{C. Bujac} et al., Qual. Theory Dyn. Syst. 15, No. 2, 327--348 (2016; Zbl 1367.34030)] for the family of cubic differential systems with the maximum number of invariant straight lines, i.e. 9 (considered with their multiplicities), the all first integrals and phase portraits were constructed.
