Title: Traveling waves and spreading speed on a lattice 
       model with age structure

Author: Zongyi Wang (Huizhou Univ., Guangdong, China)

Abstract:
 In this article, we study a lattice differential  model for a single
 species with distributed age-structure in an infinite patchy environment.
 Using method of approaches by Diekmann and Thieme, we develop a comparison
 principle and construct a suitable sub-solution to the given model,
 and show that there exists a spreading speed  of the system which
 in fact coincides with the minimal wave speed.
