Abstract.In this short paper an operator obtained by convolution with a distributional function wich belongs to the familie is presented. From it as particular cases one may obtain both, elliptic or hyperbolic Riesz potentials. Certain elementary properties are studied and the inversion problem is presented using, as principal tool, the Laplace transform.
Moreover we obtain an expression that may be interpreted as a fractional power of the ultrahyperbolic differential operator.
