Stability of Mixed Type Additive-Cubic Jensen Functional Equation in Non-Archimedean $(n,{\hat{I}}^2)$ Normed Spaces

Koushika Dhevi Sankar, Sangeetha Sampath

In this paper, we discuss the Hyers-Ulam stability of mixed-type additive-cubic Jensen functional equation \begin{align*} 2\mathcal{F}\left(\frac{2u+v}{2}\right)+2\mathcal{F}\left(…
