A Fixed Point Approach to the Fuzzy Stability of an Additive-Quadratic-Cubic Functional Equation

초록

Using the fixed point method, we prove the generalized Hyers-Ulam stability of the following additive-quadratic-cubic functional equation f (x+2y) + f(x-2y) = 2f(x+y)-2f(-x-y) + 2f(x-y) - 2f(y-x) + f(2y) + f(-2y) + 4f(-x) - 2f(x) in fuzzy Banach spaces.
