Derivations and linear functions along rational functions
The main purpose of this paper is to give characterization theorems on derivations as well
as on linear functions. Among others the following problem will be investigated: Let n ∈ Z, f …

Linked pairs of additive functions
B Ebanks - Aequationes mathematicae, 2017 - Springer
In 1990, Benz asked whether a real additive map** satisfying xf (y)= yf (x) xf (y)= yf (x) for
all points (x, y) on the unit circle must be linear. In 2005, Boros and Erdei showed that it must …
