Homomorphisms of mono-unary algebras

Evelyn M. Nelson

Vol. 99 (1982), No. 2, 427–429
Abstract

Novotny 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.
