运用重合度理论探讨了一个非线性问题的周期解,然后将其应用于零维气候系统模式的周期解问题的研究,获得了该模式存在周期解的结果。
Using Mawhin’s continuation theorem, the existence of periodic solution for a class of nonlinear problem is discussed, and then by using it, the problem of periodic solution of nonlinear model in zero-dimensional climate system is investigated. A result about the existence of periodic solution to the model is obtained.
