초록
In (J. Inequal. Appl. 2011: Article ID 55, Section 4, 2011), Jang and Park proved the Hyers-Ulam stability of quadratic *-derivations on Banach *-algebras. One can easily show that all the quadratic *-derivations delta in Section 4 must be trivial. So the results are trivial. In this paper, we correct the statements and prove the corrected results.
