Abstract

In this paper, we consider the Cauchy problem in R^N, N≥ 1 , for semi-linear Schrödinger equations with space–time fractional derivatives. We discuss the nonexistence of global L¹ or L² weak solutions in the subcritical and critical cases under some conditions on the initial data and the nonlinear term. Furthermore, the nonexistence of local L¹ or L² weak solutions in the supercritical case are studied.
