Some new stability results of a Cauchy-Jensen equation in incomplete normed spaces.

In this paper, by using a new fixed point alternative, we establish a new generalization of the Hyers-Ulam-Rassias stability concerning a Cauchy-Jensen functional equation in normed spaces which are not necessarily Banach spaces. Moreover, our paper consists of several non-trivial examples which signify the motivation of such investigations. [ABSTRACT FROM AUTHOR]
