一类捕食者-食饵模型的共存平衡态

Coexistence Steady States in a Predator-Prey Model

Christoph Walker

摘要:

研究了一类具有扩散和Holling-Tanner型非线性的年龄结构捕食系统。以捕食者生育力的强度为分支参数,证明了正共存平衡态的分支从无食饵的边缘平衡态分支出来。当猎物的生育力变化时,也会得到类似的结果。

英文摘要:

An age-structured predator-prey system with diffusion and Holling-Tanner-type nonlinearities is considered. Regarding the intensity of the fertility of the predator as bifurcation parameter, we prove that a branch of positive coexistence steady states bifurcates from the marginal steady state with no prey. A similar result is obtained when the fertility of the prey varies.
