Abstract Finding normal forms of nonintegrable Hamiltonians is a problem encountered in many branches of physics. In this article, a symbolic program is presented which uses a succession of canonical transformations to construct the Birkhoff- Gustavson normal form of a nonseparable Hamiltonian. Title of program: BIRKGUST Catalogue Id: ACHT_v1_0 Nature of problem This computer program constructs the normal form a nonintegrable Hamiltonian using Birkhoff-Gustavson Normal Form Theory.
