Stability of Solitary Waves for a Generalized Nonlinear Coupled Schrodinger Systems
In this paper we show that the standing waves of the form (e iβt u(x), e iβt u(x)), β > 0, u(x) real and positive, are stable for the systemThe Morse index of such solution is one for γ > p -1 and two for 0 < γ < p …
