HYERS-ULAM-RASSIAS STABILITY OF A QUADRATIC FUNCTIONAL EQUATION

open access: yesBulletin of the Korean Mathematical Society, 2003
Let \(X\) and \(Y\) be real vector spaces. One of main theorems of this paper states that a function \(f: X\to Y\) satisfies the functional equation \[ n^2{n-2\choose k-2}\, f\Biggl({x_1+\cdots+ x_n\over n}\Biggr)+ {n-2\choose k-1}\,\sum^n_{i=1} f(x_i)= k^2 \sum_{1\leq ...

Hyers–Ulam–Rassias Stability of Hermite’s Differential Equation

open access: yesMathematics, 2022
In this paper, we studied the Hyers–Ulam–Rassias stability of Hermite’s differential equation, using Pachpatte’s inequality. We compared our results with those obtained by Blaga et al. Our estimation for zx−yx, where z is an approximate solution and y is an exact solution of Hermite’s equation, was better than that obtained by the authors previously ...

Structural Analysis of Homomorphisms and Derivations in C∗‐Ternary Algebras Related to Additive–Quadratic Functional Equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this paper, we study algebraic structures associated with homomorphisms and derivations, which play a significant role in physics and engineering. Our main focus is on the Ulam–Hyers stability of homomorphism and derivation structures related to a class of two‐dimensional additive–quadratic functional equations in C∗‐ternary algebras.

Solutions and Stability of Triple Homoderivations Associated With Mixed 3D‐Jensen and Additive Functional Equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this paper, we introduce a new concept called mixed 3D‐Jensen and additive functional equations FEs. In the following, we demonstrate that they are additive mappings and we show that they can be C‐linear. After that, we define triple homoderivations under the above condition on triple Banach algebras (TBAs).
