Harmonic and Wave Maps Coupled with Einstein's gravitation
arXiv:1305.2110 · doi:10.1007/s10773-013-1557-8
Abstract
In this paper we discuss the coupled dynamics, following from a suitable Lagrangian, of a harmonic or wave map and Einstein's gravitation described by a metric . The main results concern energy conditions for wave maps, harmonic maps from warped product manifolds, and wave maps from wave-like Lorentzian manifolds.
