摘要：

This paper is concerned with the inhomogeneous nonlinear Shrodinger equation ( INLS-equation) iu(t) + Delta u + V (epsilon x)vertical bar u vertical bar(p)u = 0, x epsilon R-N. In the critical and supercritical cases p >= 4/N, with N >= 2, it is shown here that standing-wave solutions of ( INLS-equation) on H-1( R-N) perturbation are nonlinearly unstable or unstable by blow-up under certain conditions on the potential term V with a small epsilon > 0.
