摘要:
本文研究利用雅可比多项式对正则哈密顿系统进行辛积分。首先回顾了连续级Runge-Kutta方法的相关理论结果,随后建立基于雅可比多项式的辛方法。通过若干数值实验验证了新方法的有效性。
英文摘要:
In this paper, we study symplectic integration of canonical Hamiltonian systems with Jacobi polynomials. The relevant theoretical results of continuous-stage Runge-Kutta methods are revisited firstly and then symplectic methods with Jacobi polynomials will be established. A few numerical experiments are well performed to verify the efficiency of our new methods.
