This project concerns the analysis of Partial Differential Equations arising from quantum mechanics, geometric optics and fluid mechanic. More specifically, it focuses on the one hand on, the Nonlinear Schrödinger and Nonlinear Wave equations (as models for dispersive equations), and on the other hand on, the Navier-Stokes, Boussinesq, the primitive equations and related fluid models.Although the modeling, physical and the computational parts were very well developed for fluid models, the mathematical study did not seem to follow the same stream of progress. Meanwhile and during the last two decades, a tremendous progress has been made in the analysis of dispersive partial differential equations. So that comes the natural question on how one can use and take advantage of those new techniques and tools to further analyze the partial differential equations coming from fluid dynamic. One can already observe the beginning of this in several recent attempts. So the general purpose of this project is to bring together ideas and techniques from these seemingly different kinds of Analysis of PDEs in order to make progress on the mathematical understanding of turbulence and many other relevant physical phenomena.

该项目涉及量子力学、几何光学和流体力学产生的偏微分方程的分析，更具体地说，它一方面关注非线性薛定谔和非线性波动方程（作为色散方程的模型）。手头有纳维-斯托克斯、布辛斯克、原始方程和相关的流体模型。尽管流体模型的建模、物理和计算部分已经非常发达，但数学研究似乎并没有跟上与此同时，在过去的二十年里，色散偏微分方程的分析也取得了巨大的进步，因此自然会出现一个问题：如何使用和利用这些新技术和工具来进行分析。进一步分析来自流体动力学的偏微分方程，人们已经可以在最近的几次尝试中观察到这一点，因此该项目的总体目的是将这些看似不同类型的偏微分方程分析的思想和技术结合起来。在对湍流的数学理解上取得进展许多其他相关的物理现象。
