Stationary bands in three-dimensional Minkowski space López Camino, Rafael Lorentz manifolds Manifolds with indefinite metrics Immersions Minimal surfaces Surfaces with prescribed mean curvature In this paper we consider a free boundary problem for spacelike surfaces in the 3-dimensional Lorentz-Minkowski space L3 whose energy functional involves the area of a surface and a timelike potential. The critical points of this energy for any volume-preserving admissible variation are spacelike surfaces supported in a plane and whose mean curvature is a linear function of the time coordinate. In this paper, we consider those surfaces that are invariant in a parallel coordinate to the support plane. We call these surfaces stationary bands. We establish existence of such surfaces and we investigate their qualitative properties. Finally, we give estimates of its size in terms of the initial data. 2014-09-22T08:48:38Z 2014-09-22T08:48:38Z 2009 journal article López Camino, R.
