Standing-wave solutions to a system of non-linear Klein–Gordon equations with a small energy/charge ratio

open access: yesAdvances in Nonlinear Analysis, 2014
We prove the existence of standing-wave solutions to a system of non-linear Klein–Gordon equations on ℝN with N ≥ 3. Our solutions are characterised by a small energy/charge ratio, appropriately defined.
