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…

Nearly generalized Jordan derivations

M. Eshaghi Gordji, N. Ghobadipour

Let $A$ be an algebra and let $X$ be an $A$ -bimodule. A $C -$ linear mapping $d : A \to X$ is called a generalized Jordan derivation if there exists a Jordan derivation (in the us…

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…

Solution and stability of generalized mixed type cubic, quadratic and additive functional equation in quasi-Banach spaces

M. Eshaghi Gordji, H. Khodaei

In this paper, we achieve the general solution and the generalized Hyers-Ulam-Rassias stability of the following functional equation $$f(x+ky)+f(x-ky)=k^2f(x+y)+k^2f(x-y)+2(1-k^2)f…
