Abstract

In this paper, we solve the system of functional equations $$\begin{aligned} \textstyle\begin{cases} f(x+y)+g(y-x)=2f(x), \\ g(x+y)-f(y-x)=2g(y) \end{cases}\displaystyle \end{aligned}$$ and we investigate the stability of g-derivations in Banach algebras.

巴拿赫代数中的加法函数方程的 Pexider 系统

在本文中，我们求解了函数方程组 $$\begin{aligned}\f(x+y)+g(y-x)=2f(x), g(x+y)-f(y-x)=2g(y) \end{cases}\displaystyle \end{aligned}$$，并研究了巴拿赫代数中 g 衍生的稳定性。

期刊介绍： The aim of this journal is to provide a multi-disciplinary forum of discussion in mathematics and its applications in which the essentiality of inequalities is highlighted. This Journal accepts high quality articles containing original research results and survey articles of exceptional merit. Subject matters should be strongly related to inequalities, such as, but not restricted to, the following: inequalities in analysis, inequalities in approximation theory, inequalities in combinatorics, inequalities in economics, inequalities in geometry, inequalities in mechanics, inequalities in optimization, inequalities in stochastic analysis and applications.
