全空间上随机可压缩流鞅解的存在性及不可压缩极限

Existence of martingale solutions and the incompressible limit for stochastic compressible flows on the whole space

Prince Romeo Mensah

摘要:

本文给出了一类可压缩等熵Navier-Stokes方程组在任意随机力作用下的有限能量弱鞅解的存在性和渐近性.特别是,给定一个一般的非线性乘性噪声,我们建立了收敛到不可压缩系统的马赫数,代表的平均流速和声速之间的比率,接近零。

英文摘要:

We give an existence and asymptotic result for the so-called finite energy weak martingale solution of the compressible isentropic Navier--Stokes system driven by some random force in the whole spatial region. In particular, given a general nonlinear multiplicative noise, we establish the convergence to the incompressible system as the Mach number, representing the ratio between the average flow velocity and the speed of sound, approaches zero.
