摘要: 利用上下解方法和迭合度理论证明了人体血流Willis循环动脉瘤模型方程至少存在3个周期解, 并给出解的范围, 数值分析表明, 所得结果推广了已有的一些工作, 并解释了相关医学现象.

关键词: 动脉瘤, 迭合度, 多个周期解

Abstract: It was improved with the lower and upper method and the coincidence degree theory that there exist at least three periodic solutions for the model of aneurysm of the circle of Willis. And the domain of the solutions was given. Some known conclusions are improved. At last, we used numerical experiments to confirm the theoretical results. The theoretical results could help us to understand more aspects of aneurysm of the circle of Willis.

Key words: aneurysm, coincidence degree, multiplicity periodic solutions
