摘要
该文考虑了一类非局部扩散的SIR模型.首先,当R_(0)>1,c=c^(*)时,研究模型的临界行波解的存在性.最后,当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.
This paper is concerned with a nonlocal dispersal SIR model.We first prove the existence of critical traveling wave for this model when R_(0)>1,c=c^(*).Finally,the nonexistence of traveling wave solution for this model is established when R_(0)<1.Our results improve some known results.
