Abstract:

We discussed the existence and uniqueness, persistence, extinction and asymptotic behavior of the globally nonnegative solution of the stochastic SI system under certain conditions with Lyapunov analysis method. The stochastic SI system possesses stationary distributions and is ergodicity.

Key words:  Ito’s formula, Lyapunov method, existence and uniqueness of the positive solution; , permanence, extinction, station
