Query: On the regular space-like hypersurfaces in the de Sitter space ${\mathbb
  S}^{m+1}_{1}$ with parallel Blaschke tensors   In this paper, we use two conformal non-homogeneous coordinate systems,
modeled on the de Sitter space ${\mathbb S}^{m+1}_1$, to cover the conformal
space ${\mathbb Q}^{m+1}_1$, so that the conformal geometry of regular
space-like hypersurfaces in $\mathbb{Q}^{m+1}_1$ is treated as that of
hypersurfaces in ${\mathbb S}^{m+1}_1$. As a result, we give a complete
classification of the regular space-like hypersurfaces (represented in the de
Sitter space ${\mathbb S}^{m+1}_1$) with parallel Blaschke tensors.
