On approximate n-Jordan homomorphisms

Eszter Gselmann

Abstract

The aim of this paper it to characterize n-Jordan homomorphisms and to investigate their connection with n-homomorphisms as well as homomorphisms. Furthermore, the following implication is also verified: if a function ϕ is additive and (for a fixed integer n≥2) the mapping x ↦ ϕ(xⁿ)-ϕ(x)ⁿ satisfies some mild regularity assumption, then the function ϕ is an n-homomorphism or it is a continuous additive function.

Keywords:

homomorphism , Jordan homomorphism , n-(Jordan) homomorphism , polynomial function
