报告摘要:
Consider initial value problem for the defocusing NLS equation with nonzero background. In the soliton region |x/t|<2, Cuccagna and Jenkins obtained soliton resolution for the defocusing NLS equation; In the solitonless region |x/t|>2, we give lare time asymptotics for the defocusing NLS equation
