Stability of Quadratic Functional Equations via the Fixed Point and Direct Method
<p/> <p>Cădariu and Radu applied the fixed point theorem to prove the stability theorem of Cauchy and Jensen functional equations. In this paper, we prove the generalized Hyers-Ulam stability via the fixed point method and investigate new theorems via direct method concerning th...
