Fuzzy de Sitter space-times via coherent states quantization
Jean-Pierre Gazeau, Jihad Mourad, Julien Queva
A construction of the 2d and 4d fuzzy de Sitter hyperboloids is carried out by using a (vector) coherent state quantization. We get a natural discretization of the dS "time" axis b…

Group theoretical approach to quantum fields in de Sitter space I. The principal series
E. Joung, J. Mourad, R. Parentani
Using unitary irreducible representations of the de Sitter group, we construct the Fock space of a massive free scalar field. In this approach, the vacuum is the unique dS invarian…
