An inhomogeneous nonlinear Schrödinger equation is considered, which is invariant under -scaling. The sharp condition for global existence of -solutions is established, involving the-norm of the ground state of the stationary equation. Strong instability of standing waves is proved by constructing self-similar solutions blowing up in fi nite time.
