“…In this section, we want to investigate the conditions for existence and direction of Neimark-Sacker bifurcation at positive equilibrium point of system (5). For a similar type of discussion related to the existence and direction of Neimark-Sacker bifurcation, we refer the interested reader to [1,23,24,28,[32][33][34][35][36][39][40][41] and references therein. Notice that, the roots of characteristic polynomial (16) are conjugate complex numbers if the following condition is satisfied:…”

“…In this section, we study two feedback control strategies in order to move the unstable trajectory towards the stable one. For similar types of investigations we refer to [1,[32][33][34][35][36][37][38][39][40][41] for controlling chaos in discrete-time population models. For some other applications related to chaos control, see also [51][52][53][54][55][56][57][58][59][60][61][62].…”

In this paper, a new density-dependent host-parasitoid model is proposed. The modification is based on density-dependent factor by introducing Hassell growth function in host population. Moreover, the permanence of solutions, existence and uniqueness of positive equilibrium, local asymptotic stability and global behavior of the positive equilibrium point are also investigated. It is demonstrated that system endures Neimark-Sacker bifurcation for wide range of bifurcation parameter. In order to control chaos due to emergence of Neimark-Sacker bifurcation, two feedback control strategies, that is, OGY and hybrid control methods are implemented. Finally, all mathematical analysis, particularly, Neimark-Sacker bifurcation, chaos control strategies, and global asymptotic stability of unique positive point are verified with the help of numerical simulations.

“…In this section, we study the existence of Neimark-Sacker bifurcation for the positive steady-state .H , P / of system (3). Recently, many authors have discussed the existence of Neimark-Sacker bifurcation for discrete-time population models ( [15][16][17][18][19][20][21][22]). Various dynamical properties of a system can be discussed owing to emergence of Neimark-Sacker bifurcation.…”

We investigate the qualitative behavior of a host‐parasitoid model with a strong Allee effect on the host. More precisely, we discuss the boundedness, existence and uniqueness of positive equilibrium, local asymptotic stability of positive equilibrium and existence of Neimark–Sacker bifurcation for the given system by using bifurcation theory. In order to control Neimark–Sacker bifurcation, we apply pole‐placement technique that is a modification of OGY method. Moreover, the hybrid control methodology is implemented in order to control Neimark–Sacker bifurcation. Numerical simulations are provided to illustrate theoretical discussion.

“…If one may wish to alter the positions of positive equilibrium and to obtain its stability, to achieve the aim, one of the techniques used is to alter system structurally by introducing "indirect control" variables. Though there are many works on the single species or multispecies competition systems with feedback controls [12][13][14][15][16]. To the best of the authors' knowledge, there are still no scholars who are investigating the stability property of the 2D spatially discrete reactiondiffusion competitive system with feedback controls; this motivates us to propose such a model as follows:…”

State feedback is used to stabilize the Turing instability at the unstable equilibrium point of a discrete competitive Lotka-Volterra system. In addition, a regularization method is applied to parameter inversion for the given Turing system and numerical simulation can verify the effectiveness of the algorithm. Furthermore, how less or more sample data and dependence on the initial state affect estimation procedure are tested.
