Title: | Noncommutative de Sitter and FRW spaces | Authors: | Burić, Maja Madore, John |
Issue Date: | 1-Oct-2015 | Journal: | European Physical Journal C | Abstract: | Several versions of fuzzy four-dimensional de Sitter space are constructed using the noncommutative frame formalism. Although all noncommutative spacetimes which are found have commutative de Sitter metric as a classical limit, the algebras and the differential calculi which define them have many differences, which we derive and discuss. |
