Instability of standing waves for the inhomogeneous Gross-Pitaevskii equation

In this paper, we consider the instability of standing waves for an inhomogeneous Gross-Pitaevskii equation \[ i\psi_t +\Delta \psi -a^2|x|^2\psi +|x|^{-b}|\psi|^{p}\psi=0. \] This equation arises in the description of nonlinear waves such as propagation of a laser beam in the optical fiber. We firs...
