Centre bifurcations of periodic orbits for some special three dimensional systems
In this paper, the bifurcated limit cycles from centre for a special three dimensional quadratic polynomial system and the Lü system are studied. For a given centre, the cyclicity is bounded from below by considering the linear parts of the corresponding Liapunov quantities of the perturbed system....
