Firstly, we studied the solution of the equation where is an unknown unknown function for , is the generalized function, is a positive integer. Finally, we have studied the solution of the nonlinear
equation . It was found that the existence of the solution of such an
equation depends on the condition of and . Moreover such solution is related to the inhomogeneous wave equation depending on the conditions of , , and .
