extinction

A Levy process approach coupled to the stochastic Leslie–Gower model

This paper focuses on a two-dimensional Leslie–Grower continuous-time stochastic predator–prey system with Lévy jumps.  Firstly, we prove that there exists a unique positive solution of the system with a positive initial value.  Then, we establish sufficient conditions for the mean stability and extinction of the considered system.  Numerical algorithms of higher order are elaborated.  The obtained results show that Lévy jumps significantly change the properties of population systems.
