ResumoNovotny has presented what amounts to a necessary and sufficient condition for the existence of certain homomorphisms between mono-unary algebras.In this paper, an example is presented to show that Novotny's condition is not sufficient, and a slightly stronger condition is shown to be both necessary and sufficient.The techniques of the proof are essentially the same as those used by Novotny.
