Abstract
In this paper, we solve the following bi-additive s-functional inequalities where s is a fixed nonzero complex number with | s| ˂ 1. Moreover, we prove the Hyers-Ulam stability of quasi-*-multipliers on Banach *-algebras and unital C *algebras, associated with the bi-additive s-functional inequalities (1) and (2).
