The category of connected partial unary algebras
Homomorphisms of partial unary algebras
Existence of monomorphisms of partial unary algebras
Equation for given real functions ,
We investigate functional equations where and are given real functions defined on the set of all real numbers. For these investigations, we can use methods for constructions of homomorphisms of mono-unary algebras. Our considerations will be confined to functions which are strictly increasing and continuous on . In this case, there is a simple characterization for the existence of a solution of the above equation. First, we give such a characterization. Further, we present a construction...
