研究了一类带Holling和Leslie型反应项的捕食系统在Dirichlet边界条件下的平衡态局部分歧解与全局分歧解,给出了局部分歧解存在的充分条件和稳定性,得到了该系统平衡态的全局分歧解及其走向。
The local bifurcation and it' s stability, the global bifurcation and it' s jumps of global bifurcation solutions of steadystates in a prey-predator system with Holling and Leslie response and Dirichlet boundary conditions are investigated. The sufficient conditions for existence of bifurcating solutions of the prey-predator system and its jump are obtained.
