Stability of generalized mixed type additive-quadratic-cubic functional equation in non-Archimedean spaces
M. Eshaghi Gordji, M. Bavand Savadkouhi, Th. M. Rassias
In this paper, we prove generalized Hyres--Ulam--Rassias stability of the mixed type additive, quadratic and cubic functional equation $$f(x+ky)+f(x-ky)=k^2f(x+y)+k^2f(x-y)+2(1-k^2…
Quadratic--quartic functional equations in RN--spaces
M. Eshaghi Gordji, M. Bavand Savadkouhi, C. Park
In this paper, we obtain the general solution and the stability result for the following functional equation in random normed spaces (in the sense of Sherstnev) under arbitrary …
On approximate cubic homomorphisms
M. Eshaghi Gordji, M. Bavand Savadkouhi
In this paper, we investigate the generalized Hyers--Ulam--Rassias stability of the system of functional equations $$f(xy)=f(x)f(y), \qquad\qquad. f(2x+y)+f(2x-y)=2f(x+y)+2f(x-y)+1…

M. Eshaghi Gordji, M. Bavand Savadkouhi
We prove generalized Hyres-Ulam-Rassias stability of the cubic functional equation for all and the quartic functional…
Stability of homomorphisms and derivations in -ternary algebras
M. Bavand Savadkouhi, M. Eshaghi Gordji, N. Ghobadipour
In this paper, we investigate homomorphisms between -ternary algebras and derivations on -ternary algebras, associated with the following functional equation $$f(\frac{x_…
