ADM mass and quasilocal energy of black hole in the deformed Ho\v{r}ava-Lifshitz gravity

Understand

Inspired by the Einstein-Born-Infeld black hole, we introduce the isolated horizon to study the Kehagias-Sfetsos (KS) black hole in the deformed Ho\v{r}ava-Lifshitz gravity.

• This is because the KS black hole is more close to the Einstein-Born-Infeld black hole than the Reissner-Nordstr\"om black hole.
• We find the horizon and ADM masses by using the first law of thermodynamics and the area-law entropy.
• The mass parameter $m$ is identified with the quasilocal energy at infinity.
