Minimal Wave Speed for a Nonlocal Viral Infection Dynamical Model

Fractal 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 and traveling wave in nonlocal dispersion SIS epidemic model with delay

Boundary 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

Challenges to self-acceleration in modified gravity from gravitational waves and large-scale structure

Physics Letters B, 2017
With the advent of gravitational-wave astronomy marked by the aLIGO GW150914 and GW151226 observations, a measurement of the cosmological speed of gravity will likely soon be realised.

The minimal wave speed of the Lotka-Volterra competition model with seasonal succession

Discrete and Continuous Dynamical Systems - B, 2022
<p style='text-indent:20px;'>This paper focuses on the minimal wave speed of time-periodic traveling waves to a Lotka-Volterra competition model with seasonal succession. It is the first time the general conditions of linear selection and nonlinear selection have been derived by the comparison principle and the upper-lower solution method.

Minimal wave speed on a diffusive SIR model with nonlocal delays

Electronic 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

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

Electronic 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.
