De Sitter Space - Closed Slicing

Closed Slicing

Let

where s describe a . Then the metric reads:

Changing the time variable to the conformal time via (or equivalently ) we obtain a metric conformally equivalent to Einstein static universe:

This serves to find the Penrose diagram of de Sitter space.
