与Liebau现象有关的周期振荡的拓扑方法
A topological approach to periodic oscillations related to the Liebau phenomenon
摘要:
给出了一类与Liebau现象有关的周期边值问题正解存在、不存在和局部化的充分条件。我们的方法是拓扑性质的,并依赖于Krasnosel'ski \u的锥膨胀和压缩郭定理。我们的研究结果改进和补充了文献中的早期结果。
英文摘要:
We give some sufficient conditions for existence, non-existence and localization of positive solutions for a periodic boundary value problem related to the Liebau phenomenon. Our approach is of topological nature and relies on the Krasnosel'ski\uı-Guo theorem on cone expansion and compression. Our results improve and complement earlier ones in the literature.
