Strong instability of standing waves for nonlinear Schrödinger equations with a delta potential

Masahito Ohta, Takahiro Yamaguchi

We study strong instability (instability by blowup) of standing wave solutions for a nonlinear Schrödinger equation with an attractive delta potential and $L^{2}$ -supercritical power…

Strong instability of standing waves for nonlinear Schrödinger equations with double power nonlinearity

Masahito Ohta, Takahiro Yamaguchi

We prove strong instability (instability by blowup) of standing waves for some nonlinear Schrödinger equations with double power nonlinearity.
