Stability Results for Some Functional Equations on 2-Banach Spaces With Restricted Domains

We have a normed abelian group G,.∗,+ and a 2-pre-Hilbert space Y with linearly independent elements u and v. Our goal is to prove that any odd map f:G⟶Y satisfying the inequality fx+fy,z⩽fx+y,z,z∈u,v, for all x,y∈G with x∗+y∗≥d and some d≥0, is additive. Then, we examined the stability issue correl...
