I am reading this article http://arxiv.org/abs/hep-th/0404008 on general Kerr-de Sitter metrics.(adsbygoogle = window.adsbygoogle || []).push({});

It seems to be obvious, but I cant see the reason behind the statement that authors make after Equation 4.2 that "As the horizon is approached, the right-hand side of (4.2) approaches zero."

I would be appreciative if somebody could help me with this issue.
