Abstract

In this paper, we obtain the general solution and investigate the generalized Hyers-Ulam stability of a reciprocal type functional equation in several variables of the form \[\frac{\Pi^m_{ i=2} r(x_1 + x_i)}{\sum ^m_{i=2}[\Pi^m_{ j=2, j\neq i} r(x_1+x_j)]}=\frac{\Pi ^m _{i=1} r(x_i)}{\sum ^m_{i=2}r(x_1)[\Pi^m_{ j=2, j\neq i} r(x_j)]+ (m - 1)\Pi^m_{ i=2} r(x_i)}\] where \(m\) is a positive integer with \(m \geq 3\).
