- Abstract
- Cadariu and Radu applied the xed point method tothe investigation of Cauchy and Jensen functional equations. Inthis paper, we adopt the idea of Cadariu and Radu to prove theHyers-Ulam-Rassias stability of the quadratic functional equationfor a large class of functions from a vector space into a complete-normed space.
