摘 要:
讨论一类薛定谔方程,首先通过Fourier展开将方程化为代数方程,再用压缩映射原理证明其存在不动点,从而原方程存在拟周期解。[著者文摘]

Abstract:
we can lead to a algebraic equation by Fourier expansion for the equation β√-1)uxx+ ε|u|^2 u=εF(t,x) . Furthermore, we can prove the existence of fixed point by contraction mapping theorem. As a result, quasiperioclie solutions of the equation exist.[著者文摘]
Key words:
