# Abstract

Let \(\phi_{i}^{*}\) and \(\psi_{i} (i=0,1,...,n-1)\) are the solutions of the equations \(\boxdot^{2} - \frac{n-1}{r^{2}}\phi_{i}=0\) and \(\boxdot^{2} \psi_{i}=0\) respectively. In this paper it is shown that if \(u\) and \(v\) are satisfied by the equations \((\boxdot^{2} - \frac{n-1}{r^{2}})^{n} u = 0\) and \(\boxdot^{2n} v =0\) respectively then \(u\) and \(v\) have the representations \(u=\phi_{0}^{*} + t\phi_{1}^{*} + ... + t^{n-1}\phi_{n-1}^{*}\) and \(v = \psi_{0} + t\psi+{1} + ... + t^{n-1}\psi_{n-1}\) where \(\boxdot^{2} = \frac{1}{r^{n-1}}\frac{\partial}{\partial r} (r^{n-1} \frac{\partial}{\partial r}) - \frac{\partial^{2}}{\partial r^{2}}\).
