We are interested in the existence of travelling-waves for the nonlinear Schrödinger equation in RNwith “ψ3−ψ5”-type nonlinearity. First, we prove an abstract result in critical point theory (a local variant of the classical saddle-point theorem). Using this result, we get the existence of travelling-waves moving with sufficiently small velocity in space dimension N⩾4.
