摘要 研究如下方程的初值问题iut=Δu-|x|2u+q(|u|2)u-ia2u, x∈Rn,t>0,u(x,0)=u0(x), x∈Rn,得出当初值u0和q满足一定的条件时,该方程不存在整体解. In this paper,the following damped nonlinear Schrdinger equations with harmonic potential are studied:iu_t=Δu-|x|~2u+q(|u|~2)u-ia2u, x∈R^n, t>0,u(x,0)=u_0(x), x∈R^n.Conditions on u_0 and q are given so that solutions of equation do not exist for all t>0.
