چکیده
|
This paper is concerned with a stochastic ratio-dependent predator-prey model with varible coefficients. by the comparison theorem of stochastic equations and the itô formula,the global existence of a unique positive solution of the ratio-dependent model is obtained. besides,some results are established such as the stochastically ultimate boundedness and stochastic permanence for this model. © 2012 zheng wu et al.
