Masaru Hamano, Masahiro Ikeda

AI总结:

该文研究带排斥逆幂势的非线性薛定谔方程,证明无势情形下基态以下初值条件的等价性,并结合已有径向基态结果,得到带排斥逆幂势径向基态以下的全局适定性与“爆破或增长”结论。

摘要:

本文研究带排斥逆幂势的非线性薛定谔方程(NLS)。首先,我们给出了无势情形下基态以下的若干全局适定性结果与“爆破或增长”结果。随后,我们证明了无势情形下基态以下初值条件的等价性。需指出的是,我们近期在文献[8]中针对二维及更高空间维数下带一般势的NLS,建立了径向基态的存在性,并通过位势泛函对其进行了刻画。接着,我们还证明了在文献[8]所得的带排斥逆幂势的径向基态以下,成立一个全局适定性结果与一个“爆破或增长”结果。

英文摘要:

In this paper, we consider the nonlinear Schrödinger equation with a repulsive inverse power potential. First, we show that some global well-posedness results and "blow-up or grow-up" results below the ground state without the potential. Then, we prove equivalence of the conditions on the initial data below the ground state without potential. We note that recently, we established existence of a radial ground state and characterized it by the virial functional for NLS with a general potential in two or higher space dimensions in [8]. Then, we also prove a global well-posedness result and a "blow-up or grow-up" result below the radial ground state with a repulsive inverse power potential obtained in [8].
