Stability of additive-quadratic functional equation in modular space

General Mathematics 2024-06-25 v1

Abstract

Using the direct method, we prove the generalised Hyers-Ulam stability of the following functional equation \begin{equation} \phi(x+y, z+w)+\phi(x-y, z-w)-2 \phi(x, z)-2 \phi(x, w)=0 \end{equation} in modular space satisfying the Fatou property or Δ2\Delta_2-condition.
