Ground states of the two-dimensional dispersion managed nonlinear Schrödinger equation

Mi-Ran Choi, Young-Ran Lee

AI总结:

研究二维色散管理非线性Schrödinger方程的带质量约束变分问题,证明了极小值存在性关于质量的阈值现象,并确定了Gagliardo-Nirenberg-Strichartz型不等式的最佳常数及其极值函数。

摘要:

我们考虑源于具有幂律型非线性的二维色散管理非线性Schrödinger方程的带质量约束变分问题。证明了对于所有可能的非线性幂次(包括阈值本身),极小值存在性关于质量存在阈值现象。该阈值与Gagliardo-Nirenberg-Strichartz型不等式的最佳常数密切相关,其极值函数作为副产品被求出。

英文摘要:

We consider the variational problem with a mass constraint arising from the two-dimensional dispersion managed nonlinear Schrödinger equation with power-law type nonlinearity. We prove a threshold phenomenon with respect to mass for the existence of minimizers for all possible powers of nonlinearities, including at the threshold itself. This threshold is closely related to the best constant for the Gagliardo-Nirenberg-Strichartz type inequality whose extremizers are found as a byproduct.
