Instability theory of stationary solutions for nonlinear Schrödinger equations

Noriyoshi Fukaya, Masayuki Hayashi

We study the orbital instability of algebraically decaying stationary solutions of nonlinear Schrödinger equations in dimensions $d \geq 2$ , taking competing double-power nonlineariti…

Standing waves for defocusing nonlinear Schrödinger equations with point interaction

Noriyoshi Fukaya, Yuki Osada, Mario Rastrelli

We consider standing waves of the nonlinear Schrödinger equation $i \partial_{t} u = - Δ_{α} u + ∣ u ∣^{p - 1} u$ in the defocusing case in dimensions $N = 2$ and $N = 3$ . Here, $- Δ_{α}$ denotes the…
