A global weak solution to the Lorentzian harmonic map flow

Differential Geometry 2018-09-20 v1

Abstract

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.
