Orthogonal Stability of an Additive-Quadratic Functional Equation

Abstract Using the fixed point method and using the direct method, we prove the Hyers-Ulam stability of an orthogonally additive-quadratic functional equation in orthogonality spaces. (2010) Mathematics Subject Classification: Primar...
