초록
In this paper, we introduce and solve the following quadratic (ρ1, ρ2)-functional inequality (formala presented) in fuzzy normed spaces, where ρ1 and ρ2 are fixed nonzero real numbers with 1/|ρ1| + 1/2|ρ2| < 1, and f(0) = 0. Using the fixed point method, we prove the Hyers-Ulam stability of the quadratic (ρ1, ρ2)- functional inequality (0.1) in fuzzy Banach spaces.
