摘要
用单调迭代法并结合上下解方法研究三物种竞争系统行波解最小波速的选择机制(线性或非线性),给出速度线性选择的充分条件及最小波速非线性选择的若干新结果.所得结果扩大了线性选择的参数范围.
The selection mechanism(linear or nonlinear)of the minimum wave speed of traveling wave solutions for three species com petition system was studied by using monotone iteration method combined with upper-lower solution method.We gave the sufficient conditions for line ar selection of speed and some new results for the nonlinear selection of the minimum wave speed.The results expanded the parameter ranges of linear selection.
