This paper considers the existence and uniqueness of stochastic entropy solution for a nonlinear transport equation with a stochastic perturbation. The uniqueness is based on the doubling variable method. For the existence, we develop a new scheme of parabolic approximation motivated by the method of vanishing viscosity given by Feng and Nualart (J. Funct. Anal. 2008, 255, 313-373). Furthermore, we prove the continuous dependence of stochastic strong entropy solutions on the coefficient and the nonlinear function .
本文考虑了一类具有随机扰动的非线性输运方程随机熵解的存在性与唯一性。唯一性基于变量加倍法。对于存在性,我们受Feng和Nualart(《泛函分析杂志》2008年,255卷,313 - 373页)给出的粘性消失法的启发,发展了一种新的抛物近似格式。此外,我们证明了随机强熵解关于系数和非线性函数的连续依赖性。
