The spreading front of invasive species in favorable habitat or unfavorable habitat
Chengxia Lei, Zhigui Lin, Qunying Zhang
Spatial heterogeneity and habitat characteristic are shown to determine the asymptotic profile of the solution to a reaction-diffusion model with free boundary, which describes the…
A SIS reaction-diffusion-advection model in a low-risk and high-risk domain
Jing Ge, Kwang Ik Kim, Zhigui Lin +1
A simplified SIS reaction-diffusion-advection model is proposed and investigated to understand the impact of spatial heterogeneity of environment and advection on the persistence a…
The diffusive competition model with a free boundary: Invasion of a superior or inferior competitor
Yihong Du, Zhigui Lin
In this paper we consider the diffusive competition model consisting of an invasive species with density and a native species with density , in a radially symmetric setting…
Different Asymptotic Spreading Speeds Induced by Advection in a Diffusion Problem with Free Boundaries
Hong Gu, Zhigui Lin, Bendong Lou
In this paper, we consider a Fisher-KPP equation with an advection term and two free boundaries, which models the behavior of an invasive species in one dimension space. When sprea…
An SIR epidemic model with free boundary
Kwang Ik Kim, Zhigui Lin, Qunying Zhang
An SIR epidemic model with free boundary is investigated. This model describes the transmission of diseases. The behavior of positive solutions to a reaction-diffusion system in a…
