Abstract.Relationship between Riesz potentials and the Poisson kernel in the radial case has been studied by Samko (cf. [9]) and Rudin (cf. [8]) among others authors. The last author give a theorem that establish that the Riesz potential can be expressed as an unidimensional integral whose integrand is a Poisson's integral. In this paper analogue relations between ultrahyperbolic causal Riesz potential and causal Poisson's integral is obtained.
