Summary

Introduction

1.1 where p q n, n is the dimension of space Rn, and k is a nonnegative integer. In 2009, Saglam et al 14 have developed the operator of 1.3 , defined by 1.6 , and it is called the ultrahyperbolic Bessel operator iterated k-times. They have studied the product of the ultrahyperbolic Bessel operator related to elastic waves. Srisombat and Nonlaopon 15 have studied the weak solution of k B,c u x f x, 1.4 where u x and f x are some generalized functions They have developed 1.4 into the form m. 1.6 p q n, n is the dimension of Rn {x : x x1, x2, . . . , xn , x1 > 0, . . . , xn > 0}, Bxi ∂2/∂xi2 2vi/xi ∂/∂xi , 2vi 2βi 1, βi > −1/2, xi > 0 i 1, 2, . . . , n , f x is a given generalized function, u x is an unknown generalized function, k is a nonnegative integer, c is a positive constant, and x ∈ Rn
