On the Product of the Non-linear of Diamond Operator and

Wanchak Satsanit, Amnuay Kananthai


In this paper, we study the solution of nonlinear
where $\otimes^{k}\diamondsuit^{k}_{c_{1}}$ is the product of the
Otimes operator and Diamond operator and $\otimes^{k}$defined by
and $\diamondsuit^{k}_{c_{1}}$ defined by
 where $c_{1}$ is positive constants, $k$ is a positive integer, $p+q=n$, $n$ is the dimension of the Euclidean space
$\mathbb{R}^n$, for $x=(x_1,x_2,\ldots,x_n)\in \mathbb{R}^n$,$u(x)$
is an unknown function and $f(x,\Box^{k-1}.L^{k}\diamondsuit^{k}_{c_{1}}u(x))$ is a given function.
It was found that the existence of the solution $u(x)$ of such equation depending on the conditions of $f$ and
 $\Box^{k-1}L^{k}\diamondsuit^{k}_{c_{1}}u(x).$ \\
