Query: Rigidity theorems of the space-like $\lambda$-hypersurfaces in the
  Lorentzian space $\mathbb R^{n+1}_1$   In this paper, we study complete space-like $\lambda$-hypersurfaces in the
Lorentzian space $\mathbb R^{n+1}_1$. As the result, we prove some rigidity
theorems for these hypersurfaces including the complete space-like
self-shrinkers in $\bbr^{n+1}_1$.
