哈密顿系统的中点嵌入与变分积分

Mid-point embedding of Hamiltonian systems and variational integrators

Jacky Cresson, Rouba Safi

摘要:

根据离散嵌入形式,我们给出了J.M. Wendlandt和J.E. Marsden通过定义一个适应的二阶离散微分和积分学。这使我们能够获得离散和连续情况之间更清晰的对应关系。我们还讨论了离散哈密顿系统的相应定义。与J.M. Wendlandt和J.E.马斯登提供。

英文摘要:

Following the discrete embedding formalism, we give a new derivation of the mid-point variational integrators as developed by J.M. Wendlandt and J.E. Marsden by defining an adapted order two discrete differential and integral calculus. This allows us to obtain a clearer correspondence between the discrete and continuous case. We also discuss the corresponding definition of a discrete Hamiltonian system. A complete comparaison with the results of J.M. Wendlandt and J.E. Marsden is provided.
