Abstract: |
This paper studies a class of stochastic predator-prey models with general functional response functions. Firstly, the existence and uniqueness of the global positive solution of the model are proved. Secondly, a sufficient condition for the extinction of predator and prey is provided and proved. Finally, numerical simulation verifies the theoretical analysis results. |
