Corrigendum to “Multi-travelling waves for the nonlinear Klein-Gordon equation”

Abstract

We provide a correction to the proof of Proposition 3 by Côte and Martel [Trans. Amer. Math. Soc. 370 (2018), pp. 7461–7487]. We refer to Yuan [Nonlinearity 32 (2019), pp. 5017–5048] for a self-contained proof in the analogue context of the energy critical wave equation. We also refer to Chen and Jendrej [Trans. Amer. Math. Soc. 372 (2019), pp. 7461–7496] for an alternate proof.
