چکیده
|
Won-gil park [won-gil park, j. math. anal. appl., 376 (1) (2011) 193{202] proved the hyers-ulam stability of the cauchy functional equation, the jensen functional equation and the quadratic functional equation in 2-banach spaces. one can easily see that all results of this paper are incorrect. hence the control functions in all theorems of this paper are not correct. in this paper, we correct these results.
