Figure 4From: Dynamics analysis of a stochastic non-autonomous one-predator–two-prey system with Beddington–DeAngelis functional response and impulsive perturbationsExtinction of the prey population \(x_{2}(t)\) of system (2). (a) Time sequence diagram and (b) the phase portrait of system (2)\(.(x_{1}(0), x_{2}(0), x_{3}(0))=(0.5,0.5,0.5)\), \(\sigma _{1}^{2}(t)= \sigma _{3}^{2}(t)=0.1+0.04\sin t\), \(\sigma _{2}^{2}(t)=2.5+0.04\sin t\)Back to article page
