 De Sitter invariant special relativity

De Sitter invariant special relativity refers to a theoretical framework that extends the principles of special relativity to include de Sitter space, which is a model of spacetime that includes a positive cosmological constant. This framework can be seen as an extension of the usual flat Minkowski spacetime of special relativity, incorporating the geometric properties associated with de Sitter space, which has a constant positive curvature.
