On the Stability of Functional Equations with Square-Symmetric Operation
In this paper, we obtain the modified Hyers-Ulam-Rassias stability for the family of functional equations f (x, where H is a homogeneous function and • is a square-symmetric operation on the set S .As a consequence we obtain the Hyers-Ulam stability of its functional equation.
