1. Bifurcations in the two imaginary centers problem Creator: Chiralt, Cristina, Campos, Beatriz, and Vindel, Pura Format: bez média and svazek Type: model:article and TEXT Subject: bifurcation, topological configuration, and orbital structure Language: English Description: 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. Rights: http://creativecommons.org/publicdomain/mark/1.0/ and policy:public
