## Abst~tct For a given polynomaal tlamiltonian near an equilibrium point the program GrrA calculates analytically the normal Birkhoff-Gustavson form in Cartesian as well as angle-action coordinates and the formal integral of the motion. These quantities ate presented in the form of a truncated po

✦ Synopsis
A differential polynomial F[u] is a polynomial expression of the derivatives of the function u(x). A REDUCE program for the integration of differential polynomials is given. The program is tested on the computation of the conserved densities of polynomial evolution equations. Input and output from the test runs are included in the library files.
