چکیده
|
The concept of hyers-ulam-rassias stability has been originated from a stability theorem due to th. m. rassias. recently, the hyers-ulam-rassias stability of the functional equationf(x+2y)+ f(x-2y)= 2f(x)-f(2x)+4{f(x+y)+ f(x-y},has been proved in the case of banach spaces. in this paper, we will find out the generalized hyers-ulam-rassias stability problem of the above functional equation in random normed spaces.
