Abstract: (IOP)
From a five-dimensional Minkowski view the five-dimensional angular momentum of a free spin-0 particle moving in de Sitter spacetime is conservative, by which its timelike geodesics can be labeled completely and uniquely. Based on that observa tion and working in Beltrami coordinate for de Sitter spacetime, solutions and their asymptotic behavior to the Beltrami-de Sitter-Klein-Gordon equation are given.- space-time: de Sitter
