Some functional equations originating from number theory
arXiv:math/0310287
Abstract
We will introduce new functional equations (\ref{eq:hana}) and (\ref{eq:hana2}) which are strongly related to well-known formulae (\ref{eq:young}) and (\ref{eq:young2}) of number theory, and investigate the solutions of the equations. Moreover, we will also study some stability problems of those equations.
