Family of homoclinic orbit and homoclinic bifurcations near . (a) Family of homoclinic orbit near by making a forward continuation of the homoclinic orbit. (b) Family of homoclinic orbit near by making a backward continuation of the homoclinic orbit: the green curve denotes the Hopf curve and the blue curve denotes the homoclinic orbits.
