Dw. Qi et Zj. Jing, BIFURCATIONS OF A PAIR OF NONORIENTABLE HETEROCLINIC CYCLES, Journal of mathematical analysis and applications, 222(2), 1998, pp. 319-338
In this paper we study the bifurcations of a pair of nonorientable het
eroclinic cycles. In addition to the obvious and important bifurcation
''Omega-explosion,'' several other bifurcations, for example, homocli
nic and heteroclinic bifurcation behaviors, are described in terms of
symbolic sequences and symbolic descriptions of trajectories staying f
orever in a sufficiently small neighborhood of the cycles are establis
hed. (C) 1998 Academic Press.
