The inverse problem of the Birkhoff - Gustavson normalization and ANFER , Algorithm of Normal Form Expansion and Restoration 1
نویسنده
چکیده
In the series of papers [1-4], the inverse problem of the Birkhoff-Gustavson normalization was posed and studied. To solve the inverse problem, the symbolic-computing program named ANFER (Algorithm of Normal Form Expansion and Restoration) is written up, with which a new aspect of the Bertrand and Darboux integrability condition is found [1]. In this paper, the procedure in ANFER is presented in mathematical terminology, which is organized on the basis of the composition of canonical transformations.

In this paper, separability of the perturbed 2-dimensional isotropic harmonic oscillators with homogeneous polynomial potentials is characterized from their Birkhoff-Gustavson (BG) normalization, one of the conventional methods for non-integrable Hamiltonian systems.
متن کاملAsymptotic analysis for Schrödinger Hamiltonians via Birkhoff-Gustavson normal form
This article reviews the Birkho -Gustavson normal form theorem (BGNF) near an equilibrium point of a quantum Hamiltonian. The BGNF process is thereafter used to investigate the spectrum of Schrödinger operators in the 1:1, 1:2 and 1:3 resonances. A computer program is proposed to compute the coe cients of the BGNF up to any order.
متن کاملThe Quadratic Zeeman Effect in Hydrogen: an Example of Semi-classical Quantization of a Strongly Non-separable but Almost Integrable System
Semi-classical quantization of multidimensional systems is discussed both in terms of the Einstein-Brillouin-Keller quantization on invariant tori, and in terms of infinite families of periodic orbits. The notions of separability, integrability, and non-integrability of classical systems are introduced. An approximate integrability is used to quantize the quadratic Zeeman problem, via analytic ...
