摘要
本文考虑了一类具离散时滞的扩散Musca domestica苍蝇模型,利用上、下解方法及单调迭代技巧得到了这类模型波前解存在的充分条件。结果表明,当时滞充分小时,该模型连结两一致静态解的波前解仍能得以保持。
A type of diffusive Musca domestica houseflies models with discrete delay are concerned in this paper. By employing the upper-lower solution method and monotone iteration technique, sufficient conditions for the existence of traveling wave fronts for the above model are obtained. The results show that the traveling wave fronts connecting two uniform steady states of the model will persist when the delay is sufficiently small.
