On spectral and orbital stability for the Klein--Gordon equation coupled to an anharmonic oscillator
Andrew Comech, Elena A. Kopylova
We obtain explicit characterization of spectral and orbital stability of solitary wave solutions to the -invariant Klein--Gordon equation in one spatial dimension co…

Spectral stability and instability of solitary waves of the Dirac equation with concentrated nonlinearity
Nabile Boussaid, Claudio Cacciapuoti, Raffaele Carlone +3
We consider the nonlinear Dirac equation with Soler-type nonlinearity concentrated at one point and present a detailed study of the spectrum of linearization at solitary waves. We…
