Hyers-Ulam Stability Jensen- Cubic Function Equation

In this paper, we obtain the general solution and the Hyers-Ulam stability of the Jensen-Cubic functional equationIn first chapter, a general solution of the Jensen-Cubic functional equation is given,in chapter2, we prove the Hyers-Ulam stability for the Jensen-Cubic functional equation in Banach space, in chapter3,we prove the Hyers-Ulam stability for the Jensen-Cubic functional equation in the non-Archimedean field.
