摘要：

In this paper we calculate the particle creation as seen by a stationary observer in 3+1 de Sitter space. This particle creation is calculated using an observer-dependent geometrically based definition of time which is used to quantize a held on two different spacelike surfaces. The Bogoliubov transformation relating these two quantizations is then calculated and the resulting particle creation is shown to be finite.
