An iterative functional equation is deduced by C. T. Ng and W. Zhang 1997, J. . Differ. Equations Appl. 3, 147α168 from the problem of invariant curves. In this paper, its analytic solutions are discussed by locally reducing the equation to another functional equation without iteration and by constr
