非线性双曲平衡律中通量的正则性

Regularity of Fluxes in Nonlinear Hyperbolic Balance Laws

Matania Ben-Artzi, Jiequan Li

摘要:

本文讨论了作为积分平衡律的非线性双曲守恒律组的弱解的形式问题。其基本思想是,“有意义的对象”是通量,评估跨域边界的时间间隔。这种处理的基本结果是在多维设置中的通量迹线的规律性。这意味着一个弱解确实满足平衡定律。事实上,它表明,通量是Lipschitz连续的适当的扰动的边界。

英文摘要:

This paper addresses the issue of the formulation of weak solutions to systems of nonlinear hyperbolic conservation laws as integral balance laws. The basic idea is that the "meaningful objects" are the fluxes, evaluated across domain boundaries over time intervals. The fundamental result in this treatment is the regularity of the flux trace in the multi-dimensional setting. It implies that a weak solution indeed satisfies the balance law. In fact, it is shown that the flux is Lipschitz continuous with respect to suitable perturbations of the boundary.
