关于非线性随机平衡律

On Nonlinear Stochastic Balance Laws

Gui-Qiang G. Chen, Qian Ding, Kenneth H. Karlsen

摘要:

我们关心的是多维随机平衡律。我们确定了一类非线性平衡法,其中统一的空间$BV$界消失粘度近似可以实现。此外,我们建立时间等度连续的$L^1$的近似,一致的粘性系数。利用这些估计,我们提供了一个多维的随机熵解的存在性理论。此外,我们建立了一个误差估计的随机粘性方法,以及一个显式估计的连续依赖性的随机熵解的通量和随机源函数。各种进一步推广的结果进行了讨论。

英文摘要:

We are concerned with multidimensional stochastic balance laws. We identify a class of nonlinear balance laws for which uniform spatial $BV$ bounds for vanishing viscosity approximations can be achieved. Moreover, we establish temporal equicontinuity in $L^1$ of the approximations, uniformly in the viscosity coefficient. Using these estimates, we supply a multidimensional existence theory of stochastic entropy solutions. In addition, we establish an error estimate for the stochastic viscosity method, as well as an explicit estimate for the continuous dependence of stochastic entropy solutions on the flux and random source functions. Various further generalizations of the results are discussed.
