Instability of nonlinear bound states

Jalal Shatah, Walter Strauss

Research output: Contribution to journalArticlepeer-review


We establish a sharp instability theorem for the bound states of lowest energy of the nonlinear Klein-Gordon equation, utt-{white left-pointing small triangle}u+f(u)=0, and the nonlinear Schrödinger equation, -iut-{white left-pointing small triangle}u+f(u)=0.
