In the lines of the proof of Corollary 14 (page 25), we observed that $(u_0^2)\Rightarrow (u_0)$ and $(u_0^3)\Rightarrow (u_0)$, which are incorrect and are required to be replaced by $(u_0^1)\Rightarrow (u_0)\Rightarrow (u_0^2)$ and $(u_0^3)\Rightarrow (u_0^2)$ (as $f(X)\subseteq g(X)$). Further, we can easily prove uniqueness theorem corresponding to assumption $(u_0^2)$, whose proof is similar to that of Theorem 5 using equation (27) and then the results corresponding to conditions $(u_0)$ (i.e. Theorem 5) and $(u_0^1)$ and $(u_0^3)-(u_0^9)$ of Corollary 9 can beeasily deduced from this result.
