  • Abstract

This paper dicusses the relationship between canonical maps and generating functions and gives the general Hamilton-Jacbi theory for time-independent Hamiltonian systems. Based on this theory, the general method-the generating function method-of the construction of difference schemes for Hamiltonian systems is considered. The transition of such difference schemes from one time-step to the next is canonical. So they are called the canonical difference schemes. The well known Euler centered scheme is a canonical difference scheme. Its higher order canonical generalisations and other families of canonical difference schemes are given. The construction method proposed in the paper is also applicable to time-dependent Hamiltonian systems.
