Travelling waves in the lattice epidemic model

Electronic Journal of Differential Equations, 2010
In this article, we establish the existence and nonexistence of travelling waves for a lattice non-monotone integral equation which is an epidemic model.

Dynamics of a time-periodic and delayed reaction-diffusion model with a quiescent stage

Electronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper, we study a time-periodic and delayed reaction-diffusion system with quiescent stage in both unbounded and bounded habitat domains. In unbounded habitat domain $\mathbb{R}$, we first prove the existence of the asymptotic spreading speed and

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

Bulletin of Mathematical Biology, 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 ...

Generalized Horndeski-like Einstein Gauss-Bonnet inflation with massless primordial gravitons

Nuclear Physics B, 2021
In this work we shall introduce a theoretical framework comprised by a non-minimal coupled canonical scalar field, a non-minimal coupling to the Gauss-Bonnet invariant and a non-minimal kinetic coupling.

On the minimal speed of traveling waves for a nonlocal delayed reaction–diffusion equation [PDF]

Nonlinear Oscillations, 2010
In this note, we give constructive upper and lower bounds for the minimal speed of propagation of traveling waves for non-local delayed reaction-diffusion equation.

Wave propagation in a diffusive SEIR epidemic model with nonlocal transmission and a general nonlinear incidence rate

Boundary Value Problems, 2021
We introduce a diffusive SEIR model with nonlocal delayed transmission between the infected subpopulation and the susceptible subpopulation with a general nonlinear incidence.

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

Mathematical 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 ...

When Self-Generated Gradients interact with Expansion by Cell Division and Diffusion. Analysis of a Minimal Model

, 2022
We investigate a minimal model for cell propagation involving migration along self-generated signaling gradients and cell division, which has been proposed in an earlier study.
