Abstract. In this paper, we study the operator $\otimes^{k}_{w}$ where $\otimes^{k}_{w}$ is the operator iterated $k$ times and is defined by


where $p+q=n$ is the dimension of the Euclidean space $\mathbb{R}^n.$ At first we study the elementary solution or the Green function of the operator $\otimes^{k}_{w}$ and then such a solution is related to the solution of the Laplace equation. We found that the relationship of such solutions depending on the condition $p, q$ and k. Finally, we applied the elementary solution finding solution equation $\otimes^{k}_{w}u(x)=f(x).$ where $u(x)$ is an unknown function for $x=(x_1,x_2,\ldots,x_n)\in \mathbb{R}^n$, $f(x)$ is the generalized function, $k$ is a positive integer.
