Stability of the general form of quadratic-quartic functional equations in non-Archimedean $$\mathcal{L}$$-fuzzy normed spaces. (English) Zbl 1390.39084
Summary: In this paper, we introduce and obtain the general solution of a new generalized mixed quadratic and quartic functional equation and investigate its stability in non-Archimedean $$\mathcal{L}$$-fuzzy normed spaces.
