Approximately n--Jordan derivations: A fixed point approach

A. Ebadian

Let and let be a Banach algebra. An additive map is called n-Jordan derivation if $$D(a^n)=D(a)a^{n-1}+aD(a)a^{n-2}+...+a^{n-2}D(a)a+a^{n-1}D(a…

Stability of a functional equation deriving from cubic and quartic functions

M. Eshaghi Gordji, A. Ebadian, S. Zolfaghari

In this paper, we obtain the general solution and the generalized Ulam-Hyers stability of the cubic and quartic functional equation &4(f(3x+y)+f(3x-y))=-12(f(x+y)+f(x-y)) &+12(f(2x…
