关于Grushin Laplacian的薛定谔方程的概率局部适定性

Probabilistic local well-posedness for the Schrödinger equation posed for the Grushin Laplacian

Louise Gassot, Mickaël Latocca

摘要:

研究了随机初值下与Grushin算子相关的非线性薛定谔方程的局部适定性.据我们所知,没有适定性结果是已知的索伯列夫空间$H^k$时,$k \leq \frac{3}{2}$。在这篇文章中,我们证明了存在一个大的家庭的初始数据,使得在$H^k$,$k \in (1,\frac{3}{2}]$,几乎肯定的地方适定性持有适当的随机化。证明依赖于双线性和三线性估计。

英文摘要:

We study the local well-posedness of the nonlinear Schrödinger equation associated to the Grushin operator with random initial data. To the best of our knowledge, no well-posedness result is known in the Sobolev spaces $H^k$ when $k \leq \frac{3}{2}$. In this article, we prove that there exists a large family of initial data such that, with respect to a suitable randomization in $H^k$, $k \in (1,\frac{3}{2}]$, almost-sure local well-posedness holds. The proof relies on bilinear and trilinear estimates.
