Abstract:

In this paper, using the fixed-point and direct methods, we prove the Hyers-Ulam stability of the following m-Appolonius type functional equation:
mi=1f(z xi) = mf(z −1/m2mi=1xi)−1/m1≤i<jmf(xi + xj),
where m is a natural number greater than 1, in random normed spaces.

Key words: Hyers-Ulam stability, additive functional equation, random normed space, fixed point method
