摘要
研究一类具有依密度出生率和非选择性半封闭捕获作用项的偏害系统的动力学行为.讨论了系统平衡点的局部稳定性和全局稳定性.构造Lyapunov泛函,得到在合适的条件下4个平衡点是全局渐近稳定的,并举例说明可行性.
A non-selective harvesting amensalism model with density dependent birth rate and partial closure for the populations is proposed and studied.Local and global stability of the boundary and interior equilibriums are investigated.By constructing some suitable Lyapunov functions,all of the four equilibriums maybe globally asymptotically stable depending on some suitable assumptions.An example together with its numerical simulation is carried out to show the feasibility of the main results.
