Longtime behaviors of an epidemic model with nonlocal diffusions and a free boundary: spreading-vanishing dichotomy
Xueping Li, Lei Li
We propose a nonlocal epidemic model whose spatial domain evolves over time and is represented by with standing for the spreading front of epidemic. It is assumed…
Dynamics for a diffusive epidemic model with a free boundary: sharp asymptotic profile
Xueping Li, Lei Li, Mingxin Wang
This paper concerns the sharp asymptotic profiles of the solution of a diffusive epidemic model with one free boundary and one fixed boundary which is subject to the homogeneous Di…
Dynamics for a diffusive epidemic model with a free boundary: spreading speed
Xueping Li, Lei Li, Mingxin Wang
We study the spreading speed of a diffusive epidemic model proposed by Li et al. \cite{LL}, where the Stefan boundary condition is imposed at the right boundary, and the left bound…
The free boundary problem of an epidemic model with nonlocal diffusions and nonlocal reactions: spreading-vanishing dichotomy
Xueping Li, Lei Li, Mingxin Wang
This paper concerns the free boundary problem of an epidemic model. The spatial movements of the infectious agents and the infective humans are approximated by nonlocal diffusion o…
