With appropriately chosen parameters, there exist the black-hole horizon and the cosmological horizon in the higher-dimensional Kerr-de Sitter spacetime, where these two horizons generally have different Hawking temperatures. In this letter we first reduce the higher-dimensional Kerr-de Sitter spacetime line element to a 2-dimensional one (the (t−r) sector) using the dimensional reduction method near the cosmological horizon, and then investigate the Unruh/Hawking effects of the cosmological… CONTINUE READING
