我们考虑超临界情况下四阶非线性薛定谔方程的柯西问题 i∂ t u+ 1 4∂ x 4 u= λ∂ x (| u| ρ− 1 u),其中 ρ> 4,λε C。我们证明了小初始数据 u 0∈ H 1∩ H 1 2, 1 解的全局存在性和大时间渐近性,当阶数为非线性ρ>4。
We consider the Cauchy problem for the fourth-order nonlinear Schrödinger equation in the super critical case i∂ t u+ 1 4∂ x 4 u= λ∂ x (| u| ρ− 1 u), where ρ> 4, λ∈ C. We prove the global existence and the large time asymptotics of solutions for small initial data u 0∈ H 1∩ H 1 2, 1, when the order of the nonlinearity ρ> 4.
