A Fixed Point Approach to the Stability of a Generalized Quadratic and Additive Functional Equation
Jin, Sun Sook; Lee, Yang-Hi;

Abstract
In this paper, we investigate the stability of the functional equation $\small{f(x+2y)-2f(x+y)+2f(x-y)-f(x-2y)=0}$ by using the fixed point theory in the sense of L. C$\small{\breve{a}}$dariu and V. Radu.
