Abstract
In this paper we prove results of existence and orbital instability of periodic waves for the Klein–Gordon equation with quintic nonlinearity. The main tool used here is a recent computational approach in order to decide about the nonpositive spectrum of the linearized operator combined with the Grillakis, Shatah and Strauss’ stability theory.
