Description:  GITA: A REDUCE program for the normalization of polynomial Hamiltonians. For a given polynomial Hamiltonian near an equilibrium point the program GITA calculates analytically the normal BirkhoffGustavson form in Cartesian as well as angleaction coordinates and the formal integral of the motion. These quantities are presented in the form of a truncated power series, the highest degree of which determines the degree of the approximation. The program performs the calculation of the modified normal BirkhoffGustavson form for the Hamiltonian restricted by the resonance condition. The program package is written in the computer algebra system REDUCE.
