Abstract:

This article addresses a stochastic ratio-dependent predator-prey system with Leslie-Gower and Holling type Ⅱ schemes. Firstly, the existence of the global positive solution is shown by the comparison theorem of stochastic differential equations. Secondly, in the case of persistence, we prove that there exists a ergodic stationary distribution. Finally, numerical simulations for a hypothetical set of parameter values are presented to illustrate the analytical findings.

Key words: Stochastic ratio-dependent Holling-Tanner system, persistence in mean, stationary distribution
