Some Previous Stability Theorems Based on the Stability of the Differential
Equations for Characteristic Functions

Abstract. We reconsider two previous
stability problems in [2, 3] and give other estimations of the stable
degrees of these problems with the following metric:
λ(FX; FY)
= minT > 0 max{sup|t|>T |φX(t) – φY(t)|;
1/T}
for two distribution functions FX; FY
of two random variables X, Y and their corresponding
characteristic functions φX(t) and φY(t),
eventhough when the condition in Theorem 2.1 in [1] is not satisfied.
