Abstract

We consider the supercritical inhomogeneous nonlinear Schrödinger equation $$i\partial_t u+\Delta u+|x|^{-b}|u|^{2\sigma}u=0,$$ i ∂ t u + Δ u + | x | - b | u | 2 σ u = 0 , where $${(2 - b)/N < \sigma < (2 - b)/(N-2)}$$ ( 2 - b ) / N < σ < ( 2 - b ) / ( N - 2 ) and $${0 < b < \rm min\{2,N\}}$$ 0 < b < min { 2 , N } . We prove a Gagliardo–Nirenberg-type estimate and use it to establish sufficient conditions for global existence and blow-up in $${H^1(\mathbb{R}^N)}$$ H 1 ( R N ) .
