双曲守恒律与有限正则时空

Hyperbolic conservation laws and spacetimes with limited regularity

Philippe G. LeFloch

摘要:

流形上的双曲守恒律在地球物理流和广义相对论的许多应用中出现。作者和他的合作者最近的工作试图为黎曼流形或洛伦兹流形上定义的弱解的研究奠定基础,并包括对解的存在性和定性行为的调查。流形上的度规可以是固定的(例如球面上的浅水方程),也可以是理论的未知数之一(广义相对论的爱因斯坦-欧拉方程)。

英文摘要:

Hyperbolic conservation laws posed on manifolds arise in many applications to geophysical flows and general relativity. Recent work by the author and his collaborators attempts to set the foundations for a study of weak solutions defined on Riemannian or Lorentzian manifolds and includes an investigation of the existence and qualitative behavior of solutions. The metric on the manifold may either be fixed (shallow water equations on the sphere, for instance) or be one of the unknowns of the theory (Einstein-Euler equations of general relativity).
