一般守恒律的耗散测度值解

Dissipative measure valued solutions for general conservation laws

Piotr Gwiazda, Ondřej Kreml, Agnieszka Świerczewska-Gwiazda

摘要:

在过去的几年里,测度值解开始被认为是一个相关的概念的解决方案,如果他们满足所谓的测度值-强唯一性原则。这意味着,如果这个强解存在,则它们与源自相同初始数据的强解重合。这一性质在许多数学物理系统中得到了验证,包括不可压和可压Euler系统,可压Navier-Stokes系统等,也有一些关于一般双曲系统的结果。我们的目标是为一般系统提供一个统一的框架,这将涵盖系统中最有趣的情况,最重要的是,我们给出了方程的例子,其中的测度值-强唯一性方面还没有被考虑过,如不可压缩magentohydrodynamics和浅水磁流体力学。

英文摘要:

In the last years measure-valued solutions started to be considered as a relevant notion of solutions if they satisfy the so-called measure-valued -- strong uniqueness principle. This means that they coincide with a strong solution emanating from the same initial data if this strong solution exists. This property has been examined for many systems of mathematical physics, including incompressible and compressible Euler system, compressible Navier-Stokes system et al. and there are also some results concerning general hyperbolic systems. Our goal is to provide a unified framework for general systems, that would cover the most interesting cases of systems, and most importantly, we give examples of equations, for which the aspect of measure-valued -- strong uniqueness has not been considered before, like incompressible magentohydrodynamics and shallow water magnetohydrodynamics.
