带乘性噪声的随机守恒律的均匀化

Homogenization of Stochastic Conservation Laws with Multiplicative Noise

Hermano Frid, Kenneth H. Karlsen, Daniel Marroquin

摘要:

本文考虑了两类具有振荡系数和乘性噪声的随机守恒律的广义概周期均匀化问题。在这两种情况下的随机扰动是这样的方程承认特殊的随机解决方案发挥作用的稳态解决方案中的确定性的情况下。特别是在第二类中,这些随机解是均匀化分析中的关键要素。我们的均匀化方法是基于随机双尺度Young测度的概念,其存在性在这里建立。

英文摘要:

We consider the generalized almost periodic homogenization problem for two different types of stochastic conservation laws with oscillatory coefficients and multiplicative noise. In both cases the stochastic perturbations are such that the equation admits special stochastic solutions which play the role of the steady-state solutions in the deterministic case. Specially in the second type, these stochastic solutions are crucial elements in the homogenization analysis. Our homogenization method is based on the notion of stochastic two-scale Young measure, whose existence is established here.
