✦ Synopsis

In this Letter we obtain explicit expressions of homogeneous propagators for half-integer spin fields and their flat-space limits, showing that propagation is confined inside the light cone. Also, for lower values of spin, flat-space limits are given.

Investigation of the massive propagators allows us to exhibit indecomposable repr~'~ntations appearing with masslessness. By direct examination of the propagators, we prove that massless fields in 3 + 2 De Sitter space propagate on the light cone. Indeed, it will be shown that a choice of gauge, in
