含高阶算子的三次非线性Schrodinger方程的几乎必然局部适定性

Almost sure local well-posedness for cubic nonlinear Schrodinger equation with higher order operators

Jean-Baptiste Casteras, Juraj Foldes, Gennady Uraltsev

摘要:

本文研究了三次薛定谔方程:\[ (i \partial_t - \mathscr{L}) u = \pm |u|^2 u \quad \text{ on } I \times \mathbb{R}^d, \]在随机初值下的局部适定性,其中$\mathscr{L}$是一个$σ\geq 2$度算子.利用方向空间中的估计,我们改进和推广了标准薛定谔方程(即$\mathscr{L} = Δ$)的已知结果到任意维数,并在自然假设下得到了一般$\mathscr{L}$的结果.

英文摘要:

In this paper, we study the local well-posedness of the cubic Schrödinger equation: \[ (i \partial_t - \mathscr{L}) u = \pm |u|^2 u \quad \text{ on } I \times \mathbb{R}^d, \] with randomized initial data, and $\mathscr{L}$ being an operator of degree $σ\geq 2$. Using estimates in directional spaces, we improve and extend known results for the standard Schrödinger equation (i.e. $\mathscr{L} = Δ$) to any dimension and obtain results under natural assumptions for general $\mathscr{L}$.
