In this paper, we solve the additive π-functional equations where π is a fixed number with π 6 β 1; 2, and where π is a fixed number with π 6 β 1. Using the fixed point method, we prove the Hyers-Ulam stability of the additive π-functional equations (0.1) and (0.2) in Banach spaces.
Abstract
In this paper, we solve the additive π-functional equations where π is a fixed number with π 6 β 1; 2, and where π is a fixed number with π 6 β 1. Using the fixed point method, we prove the Hyers-Ulam stability of the additive π-functional equations (0.1) and (0.2) in Banach spaces.
