摘要
报道了一类带有扩散和时滞的捕食与被捕食系统,分析了系统的非负不变性,边界平衡点性质及全局渐近稳定性.在这个系统中,随着时滞的增加,时滞能引起稳定性,不稳定性现象.
A system of retarted functional differential equation is proposed as a predator-prey model with dispersion in the prey.The invariance of non-negativity,nature of equilibria and global stability of the system are analyzed.It is shown that in this model the time delay can cause a stable equilibrium becoming unstable.
