In this paper, by using the fixed point method, we prove two new results on the Hyers-Ulam-Rassias and the Hyers-Ulam stability for the first order delay differential equation of the formy'(t) = F(t, y(t), y(t -t )).Our results improve some related result... see more

In this paper, we prove the generalized Hyers-Ulam stability of a general k-quadratic Euler-Lagrange functional equation:for any fixed positive integer in intuitionistic fuzzy normed spaces using a fixed point method.

The purpose of this paper is to establish some  types of Ulam stability: Ulam-Hyers stability, generalized Ulam-Hyers stability, Ulam-Hyers-Rassias stability and generalized Ulam-Hyers-Rassias stability for a class of implicit fractional-order differ... see more

In this paper we will investigate the complex-valued solutions and stability of the generalized variant of Wilson’s functional equation(E) : f(xy) + ?(y)f(s(y)x) = 2f(x)g(y), x, y ? G, where G is a group, s is an involutive morphism of G and ? is a charac... see more

Using the alternative fixed point theorem, we establish the generalized Hyers—Ulam—Rassias stability of a Cauchy type functional equationfor functions takin values in arbitrary complete (real or complex)ß-normed spaces.

In this current work, we dene and nd the general solution of the tredecic functional equation. We also investigate and establish the generalized Ulam-Hyers stability of this functional equation in matrix normed spaces by using the xed point method.

The purpose of this paper is to establish some  types of Ulam stability: Ulam-Hyers stability, generalized Ulam-Hyers stability, Ulam-Hyers-Rassias stability and generalized Ulam-Hyers-Rassias stability for a class of implicit fractional-order differ... see more

Let A , B be two rings. A mapping d : A ? B is called quartic derivation, if d is a quartic function satisfies d(ab) = a4d(b) + d(a)b4 for all a, b ? A. The main purpose of this paper to prove the generalized Hyers—Ulam—Rassias stability of the ... see more

In this paper, we consider the stability problem of delay differential equations in the sense of Hyers-Ulam-Rassias. Recently this problem has been solved for bounded intervals, our result extends and improve the literature by obtaining stability in unbou... see more
