In this paper, the authors presented a novel fluid dynamics system, the forward-backward stochastic Navier-Stokes equations in two dimensions for incompressible fluid flows. The well-posedness of the system is obtained through a two-step process. First, certain projections of the system to the finite dimensions are employed, and the existence and uniqueness of solutions in finite dimensions are proved via the four step scheme. Then the Galerkin approximation is used to show the existence and uniqueness of a solution to the system in an infinite dimensional functional setup.
本文提出了一种新的流体动力学系统,即不可压缩流体流动的二维正反向随机Navier-Stokes方程。通过两步法得到了系统的适定性。首先,利用系统在有限维上的某些投影,通过四步格式证明了系统在有限维上解的存在唯一性。然后利用伽辽金近似证明了系统在无穷维函数设置下解的存在唯一性。
