摘要
本文考虑无对角时滞的ｎ种群Ｌｏｔｋａ－Ｖｏｌｔｅｒｒａ时滞系统．证明了弱对角占优（ＩＤＤ）为系统关于所有时滞全局稳定的充要条件．
N-species Lotka-Volterra systems without delayed intraspecific compe- tition are considered. It is proved that a system is globally stable for all off-diagonal delays τij ≥ 0 (i ≠ j), if and only if the interaction matrix of the system satisfies condtition (WDD).
