Minimal Wave Speed in a Predator-Prey System with Distributed Time Delay [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2018
This paper is concerned with the minimal wave speed of traveling wave solutions in a predator-prey system with distributed time delay, which does not satisfy comparison principle due to delayed intraspecific terms.

Minimal Wave Speed for a Nonlocal Viral Infection Dynamical Model

open access: yesFractal and Fractional
To provide insights into the spreading speed and propagation dynamics of viruses within a host, in this paper, we investigate the traveling wave solutions and minimal wave speed for a degenerate viral infection dynamical model with a nonlocal dispersal ...

Minimal Wave Speed in a Competitive Integrodifference System without Comparison Principle [PDF]

open access: yesMathematics, 2019
We investigate the traveling wave solutions of a competitive integrodifference system without comparison principle. In the earlier conclusions, a threshold of wave speed is defined while the existence or nonexistence of traveling wave solutions remains ...

Minimal wave speed and traveling wave in nonlocal dispersion SIS epidemic model with delay

open access: yesBoundary Value Problems
This study examines traveling wave solutions of the SIS epidemic model with nonlocal dispersion and delay. The research shows that a key factor in determining whether traveling waves exist is the basic reproduction number R 0 $R_{0}$ . In particular, the

Minimal wave speed on a diffusive SIR model with nonlocal delays

open access: yesElectronic Journal of Differential Equations, 2018
This article concerns the minimal wave speed of a diffusive SIR model with nonlocal delays, in which the dynamics of disease has no positive outbreak threshold. By constructing a pair of super and sub-solutions, we establish the existence of traveling

Traveling Waves and Estimation of Minimal Wave Speed for a Diffusive Influenza Model with Multiple Strains. [PDF]

open access: yesBull Math Biol, 2020
Antiviral treatment remains one of the key pharmacological interventions against influenza pandemic. However, widespread use of antiviral drugs brings with it the danger of drug resistance evolution. To assess the risk of the emergence and diffusion of resistance, in this paper, we develop a diffusive influenza model where influenza infection involves ...

Minimal wave speeds of delayed dispersal predator-prey systems with stage structure

open access: yesElectronic Journal of Differential Equations, 2016
This article concerns the minimal wave speed of delayed predator-prey systems with nonlocal dispersal and stage structure. By the method of upper and lower solutions, we prove the existence of positive traveling wave solutions.

Minimality conditions for wave speed in anisotropic smectic C liquid crystals [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2017
We discuss minimality conditions for the speed of monotone travelling waves in a sample of smectic C∗ liquid crystal subject to a constant electric field, dealing with both isotropic and anisotropic cases. Such conditions are important in understanding the properties of domain wall switching across a smectic layer, and our focus here is on examining ...

Spreading Speed, Traveling Waves, and Minimal Domain Size in Impulsive Reaction–Diffusion Models [PDF]

open access: yesBulletin of Mathematical Biology, 2012
How growth, mortality, and dispersal in a species affect the species' spread and persistence constitutes a central problem in spatial ecology. We propose impulsive reaction-diffusion equation models for species with distinct repro- ductive and dispersal stages.
