Abstract

In the current work, the intuitionistic fuzzy version of Hyers-Ulam stability for a nonic functional equation by applying a fixed point method is investigated. This way shows that some fixed points of a suitable operator can be a nonic mapping.

Keywords: nonic functional equation, Hyers-Ulam stability, intuitionistic fuzzy normed space
