摘要 在Dirichlet边界条件下研究一类带Ivlev反应项的捕食模型.利用谱分析和分歧理论的方法,证明了发自半平凡解的局部分歧正解的存在性,同时运用线性特征值扰动理论给出局部分歧解的稳定性.最后将局部分歧延拓为全局分歧,从而得到正解存在的充分条件. A predator-prey model with Ivlev functional response is studied under Dirichlet boundary conditions.By the spectral analysis method and the bifurcation theory,the existence of positive solutions bifurcating from the semi-trivial solutions is obtained,and some stability results are presented by linear eigenvalue perturbation theory.Moreover,making use of global bifurcation theory,two sufficient conditions for the existence of positive solutions are established.
