abstract = {The goal of the paper is to develop a method that will combine the use of variational techniques with regularization
methods in order to study existence and multiplicity results for the periodic and the Dirichlet problem associated to the
perturbed Kepler system.
The existence of critical points for the action functional
associated to the problem is proved via a non-local change
of variables inspired by Levi-Civita and Kustaanheimo-Stiefel
techniques. As an application we will prove that the perturbed
Kepler problem has infinitely many generalized T-periodic},
