摘要: In this paper,the necessary and sufficient conditions for the existence of traveling wave solutions are derived for a class of diffusive disease-transmission models with network structures.The existence of traveling semi-fronts is obtained by Schauder's fixed-point theorem and these traveling semi- fronts are shown to be bounded by transforming the boundedness problem into the classification problem of non-negative solutions to a linear elliptic system on  \mathbb\{R\}. To overcome the reducibility problem arising in the proofs, a Harnack's inequality for positive supersolutions on \mathbb\{R\} is proved.This is a joint work with Xueying Wang and Tianran Zhang.
