文摘

In this paper, we study the following time fractional Schrödinger equation where 0<α<1$0<\alpha <1$, i^α$i^{\alpha }$ denotes the principal value of i^α$i^{\alpha }$, dba27149a756271b8e23d" title="Click to view the MathML source">T>0$T>0$, λ∈C∖{0}$\lambda \in \mathbb{C}\setminus \left\{0\right\}$, p>1$p>1$, dbc" title="Click to view the MathML source">u(t,x)$u(t,x)$ is a complex-valued function, and ${}_0^C{D}_t^{\alpha }u$ denotes Caputo fractional derivative of order α.$\alpha .$ We prove that the problem admits no global weak solution with suitable initial data when 1<p<1+2∕N$1<p<1+2∕N$ by using the test function method, and also give some conditions which imply the problem has no global weak solution for every p>1$p>1$.
