The stability of additive-quadratic functional equations in paranormed spaces
In this paper, we prove the generalized Hyers-Ulam stability for the following additive-quadratic functional equation f(2x + y)− f(x + 2y) + f(x− y)− f(y − x)− 3f(x) + 3f(y) = 0 in paranormed spaces by using the fixed point method. Mathematics Subject Classification: 39B52, 39B72, 47H10
