要旨:
The scalar and electromagnetic fields of charges uniformly accelerated in de Sitter spacetime are constructed. They represent the generalization of the Born solution describing fields of two particles with hyberbolic motion in flat spacetime. In the limit Lambda->0, the Born solutions are retrieved. Since in de Sitter universe the infinities I(+/-) are spacelike, the radiative properties of the fields depend on the way in which a given point of I(+/-) is approached. The fields must involve both retarded and advanced effects: Purely retarded fields do not satisfy the constraints at the past infinity I(-)
