Özet
Öz In this article a Riemann function associated with the equation — O is estab- lished by using a suitable transformation. Also the solution of a Cauchy problem for a class of ultrahyperbolic equations is obtained by a special method of the mean value of a function on the spheres when the parameters are integers.
