TY - JOUR AU - Lee, Yang-Hi AU - Jung, Soon-Mo PY - 2020 TI - A fixed point approach to the stability of a general quartic functional equation JO - Journal of Mathematics and Computer Science SP - 207--215 VL - 20 IS - 3 AB - In this paper, we study the generalized Hyers-Ulam stability of the quartic functional equation \[ f(x+3y) - 5f(x+2y) + 10f(x+y) - 10f(x) + 5f(x-y) - f(x-2y) = 0, \] by applying the fixed point method.
