O ct 2 00 7 Boost Invariant Marginally Trapped Surfaces in Minkowski 4 - Space

چکیده
The extremal and partly marginally trapped surfaces in Minkowski 4-space, which are invariant under the group of boost isometries, are classified. Moreover, it is shown that there do not exist extremal surfaces of this kind with constant Gaussian curvature. A procedure is given in order to construct a partly marginally trapped surface by gluing two marginally trapped surfaces which are invariant under the group of boost isometries. As an application, a proper star-surface is constructed.

A local classification of spacelike surfaces in Minkowski 4-space, which are invariant under spacelike rotations, and with mean curvature vector either vanishing or lightlike, is obtained. Furthermore, the existence of such surfaces with prescribed Gaussian curvature is shown. A procedure is presented to glue several of these surfaces with intermediate parts where the mean curvature vector fiel...

Marginally trapped surfaces in Minkowski 4-space, which are invariant under a spacelike rotation, are classified based on the properties of their profile curves and the existence of such surfaces with prescribed Gaussian curvature is shown. A procedure is presented to glue several of these surfaces with intermediate parts where the mean curvature vector field vanishes.

متن کامل9 Area minimization among marginally trapped surfaces in Lorentz - Minkowski space
We study an area minimization problem for spacelike zero mean curvature surfaces in four dimensional Lorentz-Minkowski space. The areas of these surfaces are compared of with the areas of certain marginally trapped surfaces having the same boundary values. The quintessential property of zero mean curvature surfaces in Euclidean space is that they locally minimize area with respect to their boun...
