A spatial SEIRS reaction-diffusion model in heterogeneous environment

P Song, Y Lou, Y Xiao - Journal of Differential Equations, 2019 - Elsevier
We propose a susceptible-exposed-infected-recovered-susceptible (SEIRS) reaction-
diffusion model, where the disease transmission and recovery rates can be spatially …

Mathematical analysis of the dynamics of some reaction-diffusion models for infectious diseases

Y Lou, RB Salako - Journal of Differential Equations, 2023 - Elsevier

dynamics is impacted by the movement of populations and spatial heterogeneity of the …

Global dynamics of a controlled discontinuous diffusive SIR epidemic system

W Li, J Ji, L Huang, Z Guo - Applied Mathematics Letters, 2021 - Elsevier
In this work, we investigate the global dynamics of a controlled discontinuous diffusive SIR
epidemic system under Neumann boundary conditions. We first establish the conditions for …

Qualitative analysis on an SIRS reaction–diffusion epidemic model with saturation infection mechanism

C Liu, R Cui - Nonlinear Analysis: Real World Applications, 2021 - Elsevier
In this paper, we deal with an SIRS reaction–diffusion epidemic model with saturation
infection mechanism. Based on the uniform boundedness of the parabolic system, we …

Classifying the level set of principal eigenvalue for time-periodic parabolic operators and applications

S Liu, Y Lou - Journal of Functional Analysis, 2022 - Elsevier
We study the effect of diffusion and frequency on the principal eigenvalue of linear time-
periodic parabolic operators with zero Neumann boundary conditions. Monotonocity of the …

Human mobility and disease prevalence

Y Lou, RB Salako, P Song - Journal of Mathematical Biology, 2023 - Springer
We examine the effect of human mobility on disease prevalence by studying the
dependence of the total infected population at endemic equilibria with respect to population …

Control strategies for a multi-strain epidemic model

Y Lou, RB Salako - Bulletin of Mathematical Biology, 2022 - Springer
This article studies a multi-strain epidemic model with diffusion and environmental
heterogeneity. We address the question of a control strategy for multiple strains of the …

Selected topics on reaction-diffusion-advection models from spatial ecology

KY Lam, S Liu, Y Lou - arXiv preprint arXiv:2004.07978, 2020 - arxiv.org
We discuss the effects of movement and spatial heterogeneity on population dynamics via
reaction-diffusion-advection models, focusing on the persistence, competition, and evolution …

Asymptotic profiles of the endemic equilibrium of a reaction-diffusion-advection SIS epidemic model with saturated incidence rate.

R Cui - Discrete & Continuous Dynamical Systems-Series B, 2021 - search.ebscohost.com
In this paper, we consider a reaction-diffusion SIS epidemic model with saturated incidence
rate in advective heterogeneous environments. The existence of the endemic equilibrium …
