Codimension 3 heteroclinic bifurcations with orbit and inclination flips in reversible systems. (English) Zbl 1165.34358
Summary: Heteroclinic bifurcations with orbit-flips and inclination-flips are investigated in a four-dimensional reversible system by using the method originally established in D. M. Zhu [Acta Math. Sin., Engl. Ser. 14, 341–352 (1998; Zbl 0932.37032)], D. M. Zhu and Z. H. Xia [Sci. China, Ser. A 41, 837–848 (1998; Zbl 0993.34040)]. The existence and coexistence of R-symmetric homoclinic orbit and R-symmetric heteroclinic orbit, R-symmetric homoclinic orbit and R-symmetric periodic orbit are obtained. The double R-symmetric homoclinic bifurcation is found, and the continuum of R-symmetric periodic orbits accumulating into a homoclinic orbit is also demonstrated. Moreover, the bifurcation surfaces and the existence regions are given, and the corresponding bifurcation diagrams are drawn.
