A Equação de Klein-Gordon no Espaço-Tempo de Robertson-Walker

D. Gomes, E.A. Notte Cuello, E.C. de Oliveira


We obtain, using the generalized derivate operators, the second order Casimir invariant operator associated to the Fantappié-de Sitter group, isomorphic to the 5-dimensional pseudorotation group, which is the group of motions admitted by the massless Robertson-Walker cosmological spacetime.
