自然科学中测度值解的相对熵方法

Relative entropy method for measure-valued solutions in natural sciences

Tomasz Dębiec, Piotr Gwiazda, Kamila Łyczek, Agnieszka Świerczewska-Gwiazda

摘要:

在这篇文章中,我们描述了相对熵框架的应用。特别地,利用测度值熵解的概念,证明了标量守恒律的熵解的唯一性。此外,我们调查最近的结果有关测度值强唯一性的一些物理系统-不可压缩和可压缩的欧拉方程,可压缩的Navier-Stokes,多凸弹性动力学和一般双曲守恒律,以及长时间渐近的McKendrick-Von Foerster方程。

英文摘要:

In this article we describe the applications of the relative entropy framework. In particular uniqueness of an entropy solution is proven for a scalar conservation law, using the notion of measure-valued entropy solutions. Further we survey recent results concerning measure-valued-strong uniqueness for a number of physical systems - incompressible and compressible Euler equations, compressible Navier-Stokes, polyconvex elastodynamics and general hyperbolic conservation laws, as well as long-time asymptotics of the McKendrick-Von Foerster equation.
