Comment on "Generalized ternary hi-derivations on ternary Banach algebras: a fixed point approach" [Esgahi Gordji et al., J. Comput. Anal. Appl. 15 (2013) 45-54]

초록

Eshaghi Gordji et al. [10] proved the Hyers-Ulam stability of generalized ternary bi-derivations on ternary Banach algebras. It is easy to show that the resulting generalized ternary bi-derivations of [10] are meaningless, since the definition of generalized ternary bi-derivation, given in [10], is meaningless. In this paper, we correct the definition of generalized ternary bi-derivation, and correct the statements of the results and prove the corrected results.
