The stability of d'Alembert and Jensen type functional equations [PDF]

open access: yes, 2007
The aim of this paper is to study the stability problem of the d'Alembert type and Jensen type functional equations:f(x+y)+f(x+σy)=2g(x)f(y),f(x+y)+f(x+σy)=2f(x)g(y),f(x+y)+f(x+σy)=2f(x)

A d'Alembert type functional equation on semigroups

open access: yes, 2022
We treat two related trigonometric functional equations on semigroups. First we solve the $\mu$-sine subtraction law \[\mu(y) k(x \sigma(y))=k(x) l(y)-k(y) l(x), \quad x, y \in S,\] for $k, l : S\rightarrow \mathbb{C}$, where $S$ is a semigroup and ...
