Abstract
This paper is concerned with the nonexistence of global solutions to fractional in time nonlinear Schrödinger equations of the form iα∂αtω(t,z)+a1(t)Δω(t,z)+iαa2(t)ω(t,z)=ξ|ω(t,z)|p,(t,z)∈(0,∞)×RN , where N≥1 , ξ∈C{0} and p>1 , under suitable initial data. To establish our nonexistence theorem, we adopt the Pohozaev nonlinear capacity method, and consider the combined effects of absorption and dispersion terms. Further, we discuss in details some special cases of coefficient functions a1,a2∈L1loc([0,∞),R) , and provide two illustrative examples.
