GUO Zijun. A Stochastic Models on PredatorPrey Systemof Two Species with RatioDependence[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2010,49(2):48-52.DOI:
A class of predatorprey system of two species with ratiodependence is studied. According to the theory on stochastic differential equation
by constructing the Lyapunov function
and combining with stopping time and some analysis techniques
the existence and uniqueness of global solution for the system are proved. The boundedness and asymptotic estimate of the global solution are also discussed.
