二维非线性薛定谔方程和克莱因-戈登方程基态以下的散射

Scattering below the ground state for the 2D non-linear Schrödinger and Klein-Gordon equations revisited

Zihua Guo, Jia Shen

摘要:

我们重新讨论了二维质量超临界薛定谔和克莱因-戈登方程的散射问题,径向数据低于基态的能量空间。利用Dodson-Murphy \citep{dodson2017new-radial}的思想,给出了散焦和聚焦情况下能量散射的另一种证明.我们的结果还包括指数型非线性,这似乎是新的聚焦指数NLS。

英文摘要:

We revisit the scattering problems for the 2D mass super-critical Schrödinger and Klein-Gordon equations with radial data below the ground state in the energy space. We give an alternative proof of energy scattering for both defocusing and focusing cases using the ideas of Dodson-Murphy \citep{dodson2017new-radial}. Our results also include the exponential type nonlinearities which seems to be new for the focusing exponential NLS.
