摘要
利用伪概周期函数的性质和Banach压缩映像原理研究了一类常见非线性摆方程的伪概周期解问题,证明了该伪概周期解的存在性及在‖u‖L∞<1中的唯一性。
In this paper,the Nonlinear Pendulum equation is studied.The pseudo almost periodic solution is found,and its uniqueness in ‖u‖L∞1 is also got.The crucial tools in the proofs are pseudo almost periodic functions and Banach contraction mapping principle.
