On the stability of Jderivations
M. Eshaghi Gordji, S. Shams, A. Ebadian +1
In this paper, we establish the stability and superstability of derivations in algebras for the generalized Jensen--type functional equation $$rf(\frac{x+y}{r})+rf(\fra…

Stability of a mixed type quadratic, cubic and quartic functional equation
M. Eshaghi Gordji, S. Kaboli, S. Zolfaghari
In this paper, we obtain the general solution and the generalized Hyers-Ulam Rassias stability of the functional equation $$3(f(x+2y)+f(x-2y))=12(f(x+y)+f(x-y))+4f(3y)-18f(2y)+36f(…
