Lorentz调和映象流的整体弱解

A global weak solution to the Lorentzian harmonic map flow

Xiaoli Han, Lei Liu, Liang Zhao

摘要:

研究了一类抛物椭圆方程组,该方程组与从具有光滑边界的紧致Riemann曲面到具有翘曲积度量的Lorentz流形的调和映射有关。证明了该方程组存在唯一的整体弱解,且该解是正则的,除了至多有100个奇点。

英文摘要:

We investigate a parabolic-elliptic system which is related to a harmonic map from a compact Riemann surface with a smooth boundary into a Lorentzian manifold with a warped product metric. We prove that there exists a unique global weak solution for this system which is regular except for at most finitely many singular points.
