摘要

摘要:
该文研究了一类具有时间周期的空间离散多种群SIS模型的传播力学。首先，借助周期单调半流的传播速度与行波理论，证明了渐近传播速度c_*的存在性。其次，利用比较原理，证得了渐近传播速度即为单调周期行波解的最小波速。

Abstract:
The propagation dynamics was studied for a class of spatially discrete multi-type SIS epidemic model with time periodicity. Firstly, the theory of spreading speeds and travelling waves for monotonic periodic semiflows was applied to prove the existence of asymptotic spreading speed c_*. Secondly, by means of the comparison principle, the asymptotic spreading speed was proved to coincide with the minimal wave speed of monotonic periodic traveling waves.
