The zero mass limit of Kerr and Kerr-(anti-)de Sitter space-times: Revisited
arXiv:1812.11715
Abstract
We continue studying the zero mass limit of the Kerr- (Anti) de Sitter space-times by investigating the possibility of special values of the frequencies to have polynomial solutions for the radial wave equation, compute reflection coefficient for waves coming from and going to the cosmological horizon and see whether there is Hawking radiation for de Sitter geometry. We used the Parikh-Wilczek method to study this property and could not find Hawking radiation.
Still more typos. We dedicate this work to the memory of Prof. Dr. Haluk Beker, a friend and then colleague since 1955, who died swimmimg at Lombok, Indonesia
