초록

In this paper, we investigate the following orthogonally additive-quadratic functional equation f(2x+y)-f(x+2y)-f(x+y)-f(y-x)-f(x)+f(y)+f(2y)=0. and prove the generalized Hyers-Ulam stability for it in orthogonality spaces by using the fixed point method.

Abstract

In this paper, we investigate the following orthogonally additive-quadratic functional equation f(2x+y)-f(x+2y)-f(x+y)-f(y-x)-f(x)+f(y)+f(2y)=0. and prove the generalized Hyers-Ulam stability for it in orthogonality spaces by using the fixed point method.
