On the spectral stability of ground states of semi-linear Schrödinger and Klein-Gordon equations with fractional dispersion

Academic Article


  • We consider standing wave solutions of various dispersive models with non-standard form of the dispersion terms. Using index count calculations, together with the information from a variational construction, we develop sharp conditions for spectral stability of these waves.
