Nous montrons, en utilisant des idées provenant de la méthode des orbites, que toute représentation massive et d’énergie positive du groupe de Poincaré 𝒫 1,1 =SO(1,1) s 2 peut être obtenue par contraction de la série discrète de SU(1,1).

It is shown, using techniques inspired by the method of orbits, that each non-zero mass, positive energy representation of the Poincaré group 𝒫 1,1 =SO(1,1) s 2 can be obtained via contraction from the discrete series of representations of SU(1,1).
