Abstract
We study a class of threepoint functions on the de Sitter universe and on the asymptotic cone A blending of geometrical ideas and analytic methods is used to compute some remarkable integrals on the basis of a generalized startriangle identity living on the cone and on the complex de Sitter manifold We discuss an application of the general results to the study of the stability of scalar particles on the de Sitter universe
