This paper studies a nonstrictly hyperbolic system of conservation laws in one space dimension which has been proposed in the literature as mathematically natural and as a model of magnetohydrodynamic (MHD) turbulence. It is shown that the associated Riemann problem possesses a one-parameter family of different solution operators, each of which corresponds to a different ratio of two dissipation parameters that in the MHD interpretation correspond to coefficients of fluid viscosity and electrical resistivity.

守恒律对原型非严格双曲方程组解的背景粘性的依赖

SIAM数学分析期刊，第52卷，第6期，第5658-5674页，2020年1月。
本文研究了一种在空间维度上守恒律的非严格双曲系统，该系统已在文献中被提议为数学上自然的和磁流体动力学模型。 （MHD）湍流。结果表明，相关的黎曼问题拥有一个由不同解算子组成的单参数族，每个算子对应于两个耗散参数的不同比率，在MHD解释中，这两个耗散参数对应于流体粘度和电阻率的系数。
