چکیده
|
In this paper, we define and investigate the several variables mappings which are quartic in each component. we show that such mappings can be unified as an equation, say, the multi-quartic functional equation. we also establish the hyers-ulam stability of multi-quartic functional equation by a fixed point theorem in non-archimedean normed spaces. moreover, we generalize some known stability results.
