Donato, Andrea and Oliveri, Francesco (2000) Reduction to autonomous form by means of canonical variables. Memorie scientifiche di Andrea Donato, LXXVII. pp. 519-527.
In this paper it is shown to transform to autonomous form a general nonautonomous system of partial differential equations in n independent variables provides it is left invariant by n Lie groups of point transformations generating a n-dimensional Abelian Lie algebra. Two examples of physical interest are given to illustrate how the algorithm works
