摘要

在本文中，我们关注由乘法莱维噪声驱动的线性分数和分数退化随机守恒定律的算子分裂方案。更具体地说，利用经典的克鲁兹科夫变量倍增方法的变体，我们证明了分割方案生成的近似解收敛于基础问题的唯一随机熵解。最后，我们通过几个数值示例来说明收敛性分析。

Convergence of an Operator Splitting Scheme for Fractional Conservation Laws with Lévy Noise

In this paper, we are concerned with an operator-splitting scheme for linear fractional and fractional degenerate stochastic conservation laws driven by multiplicative Lévy noise. More specifically, using a variant of the classical Kružkov doubling of variables approach, we show that the approximate solutions generated by the splitting scheme converge to the unique stochastic entropy solution of the underlying problems. Finally, the convergence analysis is illustrated by several numerical examples.
