摘要
本文研究发生在某些传染病流行过程中的一个非线性积分方程的非负周期解的歧点问题,分别在已知函数有可微性假设和没有可微性假设条件下得到两个歧点存在性结果及歧点所在范围的一个估计。
In this paper we consider the bifurcation problems of a nonlinear integral equation which arise in the theory of epidemic model. We obtain two existence results of the bifurcation point in the cases which has the differentiable assumption for the nonlinear term and an estimating the range of bifurcation point respectively.
