### Abstract

In this paper, we introduce and solve the following additive (ρ_{1}, ρ_{2})-functional in-equalities [Formula presented] where ρ_{1} and ρ_{2} are fixed complex numbers with |ρ_{1}| ·|ρ_{2}| ˃ 1, and [formula presented] where ρ_{1} and ρ_{2} are fixed complex numbers with |ρ_{1}| ˃ 1. Using the fixed point method and the direct method, we prove the Hyers-Ulam stability of the additive (ρ_{1}, ρ_{2})-functional inequalities (0.1) and (0.2) in complex Banach spaces.

N2 - In this paper, we introduce and solve the following additive (ρ1, ρ2)-functional in-equalities [Formula presented] where ρ1 and ρ2 are fixed complex numbers with |ρ1| ·|ρ2| ˃ 1, and [formula presented] where ρ1 and ρ2 are fixed complex numbers with |ρ1| ˃ 1. Using the fixed point method and the direct method, we prove the Hyers-Ulam stability of the additive (ρ1, ρ2)-functional inequalities (0.1) and (0.2) in complex Banach spaces.
