nLab de Sitter spacetime

Definition

Full de Sitter spacetime is the Lorentzian manifold which is the coset space of Lorentz groups

$$dS^d \simeq O(d,1)/O(d-1,1)$$

This models a cosmology FRW model for positive cosmological constant/dark energy.

Similarly anti de Sitter spacetime is

$$adS^d \simeq O(d-1,2)/O(d-1,1)$$

(e.g. Blau §39.1)

This admits different spatial slicings of relevance:

  which concludes that with taking non-perturbative effects from membrane instantons into account one gets 4d vacua with vanishing and negative cosmological constant (Minkowski spacetime and anti-de Sitter spacetime) but not with positive cosmological constant (de Sitter spacetime). They close by speculating that M5-brane instantons might yield de Sitter spacetime.
