Abstract
We study the strong instability of ground state standing waves for the focusing -supercritical NLS with inverse-square potential where , , satisfies and . This result extends a recent result of Bensouilah et al. [On stability and instability of standing waves for the nonlinear Schrödinger equation with inverse-square potential. J. Math. Phys. 59 (2018), 101505] where the stability and instability of standing waves were shown in the -subcritical and -critical cases.
