Abstract

In this paper, the isolated horizons (IHs) with rotation are considered. It is shown that the symplectic form is the same as that in the nonrotating case. As a result, the boundary degrees of freedom can be also described by an SO $(1, 1)$ BF theory. The entropy of the rotating IH satisfies the Bekenstein–Hawking area law with the same Barbero–Immirzi parameter.
