As mentioned at the beginning, the GHY term is required to ensure the path integral (a la Hawking et al.) for quantum gravity has the correct composition properties. This older approach to path-integral quantum gravity had a number of difficulties and unsolved problems. The starting point in this approach is Feynman's idea that one can represent the amplitude WebMay 25, 2016 · In general Cai-Kim temperature is written as \(T=\frac {d_{1} H}{2\pi }\), where d 1 is a real constant and it shows deviations from Gibbons-Hawking temperature. For de-Sitter space, we have d 1 =1. So in this case the event horizon temperature is taken as Cai-Kim temperature i . e .
