In this article, a new class of real-valued Euler–Lagrange symmetry additive functional equations is introduced. The solution of the equation is provided, assuming the unknown …
In this article, a new kind of bilateral symmetric additive type functional equation is introduced. One of the interesting characteristics of the equation is the fact that it is ideal for …
In this paper, the authors introduce two new classes of series type additive functional Equations (FEs). The first class of equations is derived from the sum of the squares of the …
The analysis of stability in functional equations (FEs) within neutrosophic normed spaces is a significant challenge due to the inherent uncertainties and complexities involved. This …
This research deals with Krasnoselskii's fixed point theorem where the entries operators do not need to be G-weakly compact and contraction. These results were obtained by using the …
The Ulam stability theorem has been used in numerous functional equations to investigate the stability when a particular functional equation is approximated in Banach spaces …
