| Abstract: | the stochastic instability of Ito's stochastic differential systems isstudied. The Has'minskii theorem on stochastic instability is obviously improved. The comparison criterion of q-instability is established. Furthermore, the q-instability theorem is developed by means of the sufficient conditions reduced such that suited to applications. |
