On the stability of an AQCQ-functional equation in random normed spaces
Journal of Inequalities and Applications, 2011 In this paper, we prove the Hyers-Ulam stability of the following additive-quadratic-cubic-quartic functional equation f ( x + 2 y ) + f ( x - 2 y ) = 4 f ( x + y ) + 4 f ( x - y ) - 6 f ( x ) (1) + f ( 2 y ) + f
