两相异斑块中扩散Lotka-Volterra树系统持续生存的判据
The criteria of permanence for diffusive Lotka Volterra tree systems in two heterogeneous patches
摘要
Abstract
By introducing a concept, called the degree of a species, a set of sufficient conditions for the permanence of n-species diffusive Lotka-Volterra tree systems in two heterogeneous patches is obtained. The criteria are in explicit forms of the parameter s and thus are easily verifiable.关键词
