Translating solitons of mean curvature flow of noncompact spacelike   hypersurfaces in Minkowski space
  In this paper, we study the existence, uniqueness and asymptotic behavior of rotationally symmetric translating solitons of the mean curvature flow in Minkowski space. We also study the asymptotic behavior and the strict convexity of general solitons of such flows.
