De Sitter Group
Why is it interesting?
Layman
Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party.
Student
The de Sitter space is the curved space-time which has been most studied by quantum field theorists because it and the anti-de Sitter space are the unique maximally symmetric curved spacetimes Weinberg, 1972). Dirac Wave Equation in the de Sitter Universe E. A. Notte Cuello

"Gürsey (1963) presented the Casimir operators for the de Sitter group and concluded by showing that a particle in a de Sitter universe does not have a definite mass and spin, but definite eigenvalues of the two Casimir invariant operators of the group."Dirac Wave Equation in the de Sitter Universe E.
