Title: Klein-Gordon and Dirac equations in de Sitter space-time
Author: Notte Cuello, EA
de Oliveira, EC
Abstract: We present and discuss the Klein-Gordon and Dirac wave equations in the de Sitter universe. To obtain the Dirac wave equation we use the factorization of the second-order invariant Casimir operator associated to the Fantappie-de Sitter group. Both the Klein-Gordon and Dirac wave equations are discussed in terms of the spherical harmonics with spin weight. A particular case of Dirac wave equation is solved in terms of a new dass of polynomials.
