Instability of ground states for a quasilinear Schrödinger equation
Résumé
We study a class of one parameter (denoted by κ) family of quasi-linear Schrödinger equations arising in the theory of superfluid film in plasma physics. Using variational techniques, we prove the orbital instability of solitary waves for small values of the parameter κ, which gives an answer to a question raised in [9].
