Bifurcations in One Dimension. II. A Versal Model for Bifurcations.
Bifurcations in the two imaginary centers problem
In this paper we show that, for a given value of the energy, there is a bifurcation for the two imaginary centers problem. For this value not only the configuration of the orbits changes but also a change in the topology of the phase space occurs.
