接触Hamilton动力学的离散Hamilton-Jacobi理论

A Discrete Hamilton--Jacobi Theory for Contact Hamiltonian Dynamics

Oğul Esen, Cristina Sardón, Marcin Zajac

摘要:

本文提出了一个离散Hamilton-Jacobi理论,用于定义在(离散)接触流形上的(离散)Hamilton动力学。为此,我们首先提供了一个新的几何Hamilton-Jacobi理论的连续接触哈密顿动力学。然后,基于离散接触拉格朗日方程,通过离散勒让德变换得到了哈密顿动力学的离散方程。基于离散的接触Hamilton方程,构造了接触Hamilton动力学的离散Hamilton-Jacobi方程.我们展示了如何离散的Hamilton-Jacobi方程与连续的Hamilton-Jacobi理论在这项工作中提出。然后,我们提出了接触流形上的离散Hamilton-Jacobi方程的离散接触流的几何基础。最后给出了一个数值例子来验证理论。

英文摘要:

In this paper, we propose a discrete Hamilton--Jacobi theory for (discrete) Hamiltonian dynamics defined on a (discrete) contact manifold. To this end, we first provide a novel geometric Hamilton--Jacobi theory for continuous contact Hamiltonian dynamics. Then, rooting on the discrete contact Lagrangian formulation, we obtain the discrete equations for Hamiltonian dynamics by the discrete Legendre transformation. Based on the discrete contact Hamilton equation, we construct a discrete Hamilton--Jacobi equation for contact Hamiltonian dynamics. We show how the discrete Hamilton--Jacobi equation is related to the continuous Hamilton--Jacobi theory presented in this work. Then, we propose geometric foundations of the discrete Hamilton--Jacobi equations on contact manifolds in terms of discrete contact flows. At the end of the paper we provide a numerical example to test the theory.
