摘要
The study of spatially explicit integro-difference systems when the local 族群 dynamics are given in terms of discrete-time generations models has gained considerable attention over the past two decades. These 非線性 systems arise naturally in the study of the spatial dispersal of organisms. The brunt of the 數學 research on these sytems, particularly, when dealing with cooperative systems, has focused on the study of the existence of traveling wave solution and the characterization of their spreading speed. Here, we characterize the minimum propagation (spreading) speed, via the convergence of initial data to wave solutions, for a large class of non cooperative 非線性 systems of integro-difference equations. The spreading speed turns out to be the slowest speed fro, a family of non-constant traveli
