A class of cubic differential systems with 6-tuple focus. (English) Zbl 0712.34044

Author’s abstract: This paper presents a class of cubic differential systems with the origin as a 6-tuple focus from which 6 limit cycles may be constructed. For this class of differential systems the stability of the origin is given.
