Chapter Chapter 6 in Symplectic Geometric Algorithms for Hamiltonian Systems, 2010, pp 249-275 from Springer

Abstract: Abstract In the previous chapter, we constructed the symplectic schemes of arbitrary order via generating function. However the construction of generating functions is dependent on the chosen coordinates. One would like to know under what circumstance will the construction of generating functions be independent of the coordinates. The generating functions are deeply associated with the conservation laws, so it is important to study their properties and computations.
