چکیده انگلیسی
We prove that every bound state of the nonlinear Schrödinger equation (NLS) with Morse index equal to two, with d2dω2(E(ϕω)+ωQ(ϕω))>0, is orbitally unstable. We apply this result to two particular cases. One is the NLS equation with potential and the other is a system of three coupled NLS equations. In both the cases the linear instability is well known but the orbital instability results are new when the spatial dimension is high.
