Functional Analysis 2025-05-14 v1

Abstract

In this paper, we study the Hyers-Ulam stability of the following equation \begin{multline*} \phi(x+y-z)+\phi(x+z-y)+\phi(y+z-x)=\phi (x-y)+\phi(x-z)+\phi(z-y) +\phi(x)+\phi(y) +\phi(z) \end{multline*} in modular space, with or without Δ2\Delta_2-condition, and in β\beta-homogeneous Banach space.
