چکیده
Numerical convergence of a Telegraph Predator-Prey system is studied. This partial differential equation (PDE) can describe various biological systems with reactive, diffusive, and delay effects. Initially, the PDE was discretized by Finite Differences method. Then, equations in time-explicit form space-implicit obtained. The consistency discretization verified. Von Neumann stability conditions were calculated for reactive terms Delayed system. On other hand, our system, it not possible to obtain von analytically. In this context, numerical experiments carried out verified that mesh refinement model parameters, constants, diffusion coefficients determine stability/instability equations. results presented.

متن کاملEvolution of Lotka-Volterra predator-prey systems under telegraph noise.
In this paper we study a Lotka-Volterra predator-prey system with prey logistic growth under the telegraph noise. The telegraph noise switches at random two prey-predator models. The aim of this work is to determine the subset of omega-limit set of the system and show out the existence of a stationary distribution. We also focus on persistence of the predator and thus we look for conditions tha...
متن کاملStability analysis of a fractional order prey-predator system with nonmonotonic functional response
In this paper, we introduce fractional order of a planar fractional prey-predator system with a nonmonotonic functional response and anti-predator behaviour such that the adult preys can attack vulnerable predators. We analyze the existence and stability of all possible equilibria. Numerical simulations reveal that anti-predator behaviour not only makes the coexistence of the prey and predator ...
متن کاملNumerical-analytical solutions of predator-prey models
This paper deals with the construction of piecewise analytic approximate solutions for nonlinear initial value problems modeled by a system of nonlinear ordinary differential equations. In real world several biological and environmental parameters in the predator-prey model vary in time. Thus, non-autonomous systems are important to be studied. We show the effectiveness of the method for autono...
