一维NLS中结合非线性的有限时间爆炸准则

Blow-up criteria for the 1D NLS with combined nonlinearities

AI总结:

本文提出了一种用于一维NLS中结合非线性有限时间爆炸解的负能量和正能量准则,并给出了满足这些准则的初始数据示例。

摘要:

本文发展了两种不同的准则,用于确定一维结合非线性薛定谔方程有限时间爆炸解的条件。第一种是针对三重结合非线性发展的负能量准则,随后推广到收敛的无限级数中的结合非线性,包括指数非线性。第二种是针对双重非线性的正能量准则,其中包含反聚焦-聚焦系数。我们还提供了初始数据的例子,这些数据满足上述任一准则。

英文摘要:

In this paper we develop two different types of criteria for the finite time blow-up solutions to the combined nonlinear Schrödinger equation in 1D. The first one is a negative energy criterion developed for triple combined nonlinearity and then for a (convergent) infinite sum of combined nonlinearities, including an exponential nonlinearity. The second one is a positive energy criterion for the double nonlinearity with the defocusing-focusing coefficients. We also provide examples of initial data that satisfy either of the criteria.
