Spatial dynamics of an epidemic model with nonlocal infection

ZG Guo, GQ Sun, Z Wang, Z Jin, L Li, C Li - Applied Mathematics and …, 2020 - Elsevier
Nonlocal infection plays an important role in epidemic spread, which can reflect the real
rules of infectious disease. To understand its mechanism on disease transmission, we …

Interactions of diffusion and nonlocal delay give rise to vegetation patterns in semi-arid environments

Q Xue, C Liu, L Li, GQ Sun, Z Wang - Applied Mathematics and …, 2021 - Elsevier
Vegetation pattern is caused by local instability in phase space, which can reflect the
distribution characteristics of vegetation in the studied space. In semi-arid environment, the …

Spatiotemporal dynamics of a vegetation model with nonlocal delay in semi-arid environment

Q Xue, GQ Sun, C Liu, ZG Guo, Z Jin, YP Wu… - Nonlinear …, 2020 - Springer
Vegetation patterns can reflect the spatial distribution of vegetation in both space and time.
In semi-arid regions, the absorption of water by vegetation is a nonlocal process meaning …

Mathematical analysis of epidemic models with treatment in heterogeneous networks

Y Wang, J Cao, C Xue, L Li - Bulletin of Mathematical Biology, 2023 - Springer
In this paper, we formulate two different network-based epidemic models to investigate the
effect of partly effective treatment on disease dynamics. The first network model represents …
