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 $$rf(\frac{x+y}{r})+rf(\fra…
Inequalities for the Polar Derivative of a Polynomial
M. Shakeri, M. Bidkham, M. Eshaghi Gordji
In this paper we obtain new results concerning maximum modulus of the polar derivative of a polynomial with restricted zeros. Our results generalize and refine upon the results of…
On systems of nonlinear equations
M. Eshaghi Gordji, A. Ebadian, M. B. Ghaemi +1
In this paper, we introduce an iterative numerical method to solve systems of nonlinear equations. The third-order convergence of this method is analyzed. Several examples are give…
Quadratic--quartic functional equations in RN--spaces
M. Eshaghi Gordji, M. Bavand Savadkouhi, C. Park
In this paper, we obtain the general solution and the stability result for the following functional equation in random normed spaces (in the sense of Sherstnev) under arbitrary …
Stability of a mixed type quadratic, cubic and quartic functional equation
M. Eshaghi Gordji, S. Kaboli, S. Zolfaghari
In this paper, we obtain the general solution and the generalized Hyers-Ulam Rassias stability of the functional equation $$3(f(x+2y)+f(x-2y))=12(f(x+y)+f(x-y))+4f(3y)-18f(2y)+36f(…
