Abstract

In this research paper, the authors present a new mixed Euler-Lagrange

σ

-cubic-quartic functional equation. For this introduced mixed type functional equation, the authors obtain general solution and investigate the various stabilities related to the Ulam problem in Felbin’s type of fuzzy normed linear space (f-NLS) with suitable counterexamples. This approach leads us to approximate the Euler-Lagrange

σ

-cubic-quartic functional equation with better estimation.
