Soga(2015)阐明了应用于双曲标量守恒律和由Tonelli型时空相关通量函数生成的Hamilton-Jacobi方程的Lax-Friedrichs方案的随机和变分方面。本文推广了Lax-Friedrichs格式的结果,证明了其时间全局稳定性、大时间行为和误差估计。还提供了离散方程的弱KAM类定理,该定理在弱KAM理论的数值分析和模拟中是有用的。作为一个应用,有限差分近似有效的哈密顿和KAM环面严格处理。证明基本上依赖于变分法的Lax-Friedrichs计划和理论上的粘度解决方案的Hamilton-Jacobi方程。引用
A stochastic and variational aspect of the Lax-Friedrichs scheme applied to hyperbolic scalar conservation laws and Hamilton-Jacobi equations generated by space-time dependent flux functions of the Tonelli type was clarified by Soga (2015). The results for the Lax-Friedrichs scheme are extended here to show its time-global stability, the large-time behavior, and error estimates. Also provided is a weak KAM-like theorem for discrete equations that is useful in the numerical analysis and simulation of the weak KAM theory. As one application, a finite difference approximation to effective Hamiltonians and KAM tori is rigorously treated. The proofs essentially rely on the calculus of variations in the Lax-Friedrichs scheme and on the theory of viscosity solutions of Hamilton-Jacobi equations. References
