Instability for standing waves of nonlinear Klein-Gordon equations via mountain-pass arguments
Louis Jeanjean, Stefan Le Coz
We introduce mountain-pass type arguments in the context of orbital instability for Klein-Gordon equations. Our aim is to illustrate on two examples how these arguments can be usef…

A note on Berestycki-Cazenave's classical instability result for nonlinear Schrödinger equations
Stefan Le Coz
In this note we give an alternative, shorter proof of the classical result of Berestycki and Cazenave on the instability by blow-up for the standing waves of some nonlinear Schrödi…
