Query: Entire scalar curvature flow and hypersurfaces of constant scalar
  curvature in Minkowski space   We prove existence in the Minkowski space of entire spacelike hypersurfaces
with constant negative scalar curvature and given set of lightlike directions
at infinity; we also construct the entire scalar curvature flow with prescribed
set of lightlike directions at infinity, and prove that the flow converges to a
spacelike hypersurface with constant scalar curvature. The proofs rely on
barriers construction and a priori estimates.
