本文研究了具有和不具有拟单调条件的时滞单稳态传染病模型整体解的存在性。在拟单调情形下,我们首先建立比较原理,构造适当的子解和上估计。然后通过混合任意有限个不同速度c ≥ cmin和方向的波前与一个空间独立解,证明了整体解的存在性和定性特征,其中cmin > 0是临界波速.在非拟单调情形下,利用两个辅助拟单调系统的行波阵面和空间独立解以及三个系统Cauchy问题的比较定理,构造了一些新的整体解.
The purpose of this work is to study the existence of entire solutions for delayed monostable epidemic models with and without the quasimonotone condition. In the quasi-monotone case, we first establish the comparison principle and construct appropriate sub-solutions and upper estimates. Then the existence and qualitative features of entire solutions are proved by mixing any finite number of traveling wave fronts with different speeds c ≥ cmin and directions and a spatially independent solution, where cmin > 0 is the critical wave speed. In the non-quasi-monotone case, some new types of entire solutions are constructed by using the traveling wave fronts and spatially independent solutions of two auxiliary quasi-monotone systems and a comparison theorem for the Cauchy problems of the three systems.
