摘 要: 本文研究动力系统周期解的同伦方法.首先将周期解的定解问题转化为非线性代数方程组,给出其单调同伦求解方法.并利用数值积分方法确定代数方程组的值及其Jacobi矩阵,从而证明了数值解的存在性并出其误差估计. This paper deals with the homotopy methods for solving periodic solutions of dynamical systems. The problem for periodic solutions is formulated into the nonlinear algebraic system. Then a monotone homotopy method is proposed to solve the nonlinear system. To evaluate the value and its Jacobian matrix a numerical integration method is employed. The error estimate of the numerical solution is also given. Fianlly a numerical example is given to illustrate the effectiveness of the method.
