On approximate n-ring homomorphisms and n-ring derivations

M. Eshaghi Gordji

Let $A, B$ be two rings and let $X$ be an $A -$ module. An additive map $h : A \to B$ is called n-ring homomorphism if $h (Π_{i = 1}^{n} a_{i}) = Π_{i = 1}^{n} h (a_{i}),$ for all $a_1,a_2, ...,a_n \in…

Stability of cubic and quartic functional equations in non-Archimedean spaces

M. Eshaghi Gordji, M. Bavand Savadkouhi

We prove generalized Hyres-Ulam-Rassias stability of the cubic functional equation $f (k x + y) + f (k x - y) = k [f (x + y) + f (x - y)] + 2 (k^{3} - k) f (x)$ for all $k \in N$ and the quartic functional…

n-Jordan homomorphisms

M. Eshaghi Gordji

Let $n \in N,$ and let $A, B$ be two rings. An additive map $h : A \to B$ is called n-Jordan homomorphism if $h (a^{n}) = (h (a))^{n}$ for all $a \in A$ . Every Jordan homomorphism is an…
