-
摘要: 研究了离散型二维竞争系统的渐近稳定性,得到了这类竞争系统中各类平衡点的坐标及其性质,获得了系统在边界上的平衡点处渐近稳定的一系列充分条件.这些条件等价于该系统中的某个群体在竞争过程中消亡或被淘汰的相应条件.Abstract: The asymptotic stability of discrete two-dimensional competitive system has been discussed. The coordinates and properties of various types of equilibrium in such competition systems has been obtained. Some sufficient conditions of asymptotic stability for the equilibriums on border in such system has been obtained, which is equivalent to the conditions of extinction of some groups in this competitive system.
