Stability and Hopf bifurcation analysis for a Lotka-Volterra predator-prey model with two delays. (English) Zbl 1231.34151
A two-species Lotka-Volterra predator-prey model with two delays is considered. By analyzing the associated characteristic transcendental equation, the linear stability of the positive equilibrium is investigated and Hopf bifurcation is demonstrated. Some numerical simulations for supporting the theoretical results are also included.
