Abstract

In this paper we are concerned with the study of the existence and multiplicity of connecting orbits for a singular planar Newtonian system \({\ddot{q} + V_q(t, q) = 0}\) with a periodic strong force Vq(t, q), an infinitely deep well of Gordon's type at one point and two stationary points at which a potential V (t, q) achieves a strict global maximum. To this end we minimize the corresponding actiön functional over the classes of functions in the Sobolev space \({W^{1, 2}_{\rm loc}(\mathbb{R}, \mathbb{R}^2)}\) that turn a given number of times around the singularity.
