• Bi-center problem and bifurcation of limit cycles from nilpotent singular points in Z2-equivariant cubic vector fields (2018, background): “H(3) 13 was proved in [22,23] and H(4) 16 was obtained in [41,42].”
• Bifurcation of limit cycles at infinity in piecewise polynomial systems (2018, background): “On the other hand, Liu and Li [8] investigated the cyclicity problem for a Z2-equivariant cubic system, and showed that this system can have 13 limit cycles, with a large-amplitude limit cycle at infinity, surrounding 12 small-amplitude limit cycles around two symmetric foci.”
