Difference polynomials and their generalizations

Mathematika, 2001
\textit{A. Ehrenfeucht} [Pr. Mat. 2, 167--169 (1956; Zbl 0074.25505)] proved that a difference polynomial \(f(X)-g(Y)\) in two variables \(X,Y\) with complex coefficients is irreducible provided that the degrees of \(f\) and \(g\) are coprime. \textit{G.

Polynomials and divided differences

Publicationes Mathematicae Debrecen, 2005
\textit{J. Aczél} showed in 1963 [see Math. Mag. 58, 42--45 (1985; Zbl 0571.39005)] that there is a simple functional equation involving two unknown functions, say \(f\) and \(g\), whose general solution (no regularity conditions whatever) is: \(f\) is a polynomial of degree at most 2 and \(g\) is the derivative of \(f\).

Remarks on Difference-Polynomials

Bulletin of the London Mathematical Society, 1985
A polynomial of the form \(f(x)-g(y),\) where x and y are disjoint finite sets of variables, is called a difference polynomial. Let \(P(x)-Q(y)\) and \(P^*(x)-Q^*(y)\) be two difference-polynomials having an irreducible common factor F. The main theorem of this article establishes the existence of a difference polynomial f(x)-g(y) which is divisible by

On properties of difference polynomials

Acta Mathematica Scientia, 2011
Abstract We study the value distribution of difference polynomials of meromorphic functions, and extend classical theorems of Tumura-Clunie type to difference polynomials. We also consider the value distribution of f(z)f(z+c) .
