Minimal Wave Speed of a Nonlocal Diffusive Epidemic Model with Temporal Delay
نویسندگان
چکیده
This note is concerned with a nonlocal version of the man-environment-man epidemic model in which the dispersion of infectious agents is assumed to follow a nonlocal diffusion law modeled by a convolution operator. The purpose of this note is to show that the minimal wave speeds of properly re-scaled nonlocal diffusion equations can approximate the corresponding one of the classical diffusion equation for this model. As a byproduct, our results indicate that the temporal delay in an epidemic model can reduce the speed of epidemic spread while the nonlocal effect can increase the speed.

Travelling waves of a diffusive Kermack–McKendrick epidemic model with non-local delayed transmission
We obtain full information about the existence and non-existence of travelling wave solutions for a general class of diffusive Kermack–McKendrick SIR models with nonlocal and delayed disease transmission. We show that this information is determined by the basic reproduction number of the corresponding ordinary differential model, and the minimal wave speed is explicitly determined by the delay ...
متن کاملOn the Diffusive Nicholson's Blowflies Equation with Nonlocal Delay
This paper is concerned with the diffusive Nicholson’s blowflies model with nonlocal (or spatiotemporal) delay. When the spatial variable is one-dimensional, we establish the existence of travelling wave-front solutions by using the approach developed by Wang, Li, and Ruan (J. Differ. Equ. 222, 185–232, 2006) on the existence of travelling front solutions of reaction–diffusion systems with nonl...
متن کاملTraveling Waves of a Mutualistic Model of Mistletoes and Birds
The existences of an asymptotic spreading speed and traveling wave solutions for a diffusive model which describes the interaction of mistletoe and bird populations with nonlocal diffusion and delay effect are proved by using monotone semiflow theory. The effects of different dispersal kernels on the asymptotic spreading speeds are investigated through concrete examples and simulations.
متن کاملTraveling Fronts in Monostable Equations with Nonlocal Delayed Effects
In this paper, we study the existence, uniqueness and stability of traveling wave fronts in the following nonlocal reaction–diffusion equation with delay ∂u (x, t) ∂t = d u (x, t)+ f ⎛ ⎝u (x, t) , ∞ ∫ −∞ h (x − y) u (y, t − τ) dy ⎞ ⎠. Under the monostable assumption, we show that there exists a minimal wave speed c∗ > 0, such that the equation has no traveling wave front for 0 < c < c∗ and a tr...
متن کاملInstability in Diffusive Ecological Models with Nonlocal Delay Effects
We propose a reaction diffusion system with nonlocal delays to model the growth of plankton communities feeding on a limiting nutrient supplied at a constant rate. Two delays are incorporated into the model: one describes the delayed nutrient recycling process and the other models the delayed growth response of the plankton. It is assumed that both delays are nonlocal in the sense that there ar...
