Functional inequalities in fuzzy normed spaces


In this paper, we solve the following additive functional inequality (Formula presented) and the following quadratic functional inequality (Formula presented) in fuzzy normed spaces. Using the fixed point method, we prove the Hyers-Ulam stability of the additive functional inequality (0.1) and the quadratic functional inequality (0.2) in fuzzy Banach spaces.
