摘要:

该文考虑了一类非局部扩散的SIR模型. 首先, 当$ {\cal R}_0>1 $, c=c*时, 研究模型的临界行波解的存在性. 最后, 当$ {\cal R}_0<1 $时, 讨论模型的行波解的不存在性. 完善了已有文献的一些结果.

关键词: 非局部扩散, SIR模型, 临界波速, 行波解

Abstract:

This paper is concerned with a nonlocal dispersal SIR model. We first prove the existence of critical traveling wave for this model when $ {\cal R}_0>1 $, $ c=c^* $. Finally, the nonexistence of traveling wave solution for this model is established when $ {\cal R}_0<1 $. Our results improve some known results.

Key words: Nonlocal dispersal, SIR model, Critical wave speed, Traveling wave
