Query: Rotational Dragging Effect on Statistical Thermodynamics of
  (2+1)-dimensional Rotating de Sitter Space   Brief comments on a plausible holographic relationship between the opposite
rotational dragging effect of a (2+1)-dimensional rotating de Sitter space and
the non-unitarity of a boundary conformal field theory are given. In addition
to the comments, we study how the opposite rotational dragging effect affects
the statistical-mechanical quantities in the rotating de Sitter space in
comparison with a BTZ black hole.
