Stability of a Class of Mixed Functional Equations in Banach Space
A new class of cubic and quartic mixed functional equations was presented and its general solution in vector space was obtained.Combined with the definition of difference operator,the generalized Hyers-Ulam-Rassias stability of the mixed functional equation on Banach space was proved by direct method.
