The solution of some persistent $p : -q$ resonant center problems
The notion of $p:-q$ resonant center was introduced recently and studied by several authors. In this paper we generalize the notion of a persistent center to a persistent $p:-q $ resonant center and find conditions for existence of a persistent $p:-q$ resonant center for several $p:-q$ resonant sys...
