“…Recently, many theoreticians and experimentalists have discussed dynamical behavior of prey-predator system with Holling-Tanner functional response, it reveals that time delay may cause the loss of stability and other complicated dynamical behavior such as the periodic structure and bifurcation phenomenon [29,31,32,35,41,44,47]. By considering time delay for both prey and predator population, system (3) is extended in [47], which is as follows:…”
