چکیده
A program to compute the Birkhoo normal forms for symplectic maps in l R 4 is described. We consider the case of an elliptic xed point, which is the most relevant for applications. We compute the normal forms both in the nonresonant and resonant case and we provide the interpolating hamiltonian and the normalizing transformation. Programming language: Fortran 77. High speed storage required: 1.2 Mb at perturbative order 10. Peripheral used: Storage for input and output les. No. of lines in combined program and test deck: 1063.

REGULAR ARTICLES Twist singularities for symplectic maps
Near a nonresonant, elliptic fixed point, a symplectic map can be transformed into Birkhoff normal form. In these coordinates, the dynamics is represented entirely by the Lagrangian ‘‘frequency map’’ that gives the rotation number as a function of the action. The twist matrix, given by the Jacobian of the rotation number, describes the anharmonicity in the system. When the twist is singular the...
متن کاملExistence of Divergent Birkhoff Normal Forms of Hamiltonian Functions
where κ = 0, . . . , n, and λj is pure imaginary precisely when 1 ≤ j ≤ κ, and λ1, −λ1, . . . , λn, −λn are eigenvalues of Hzz(0)J with z = (x, y) and Jxj = yj = −J yj. One says that λ1, . . . , λn are non-resonant, if λ ·α ≡ λ1α1 + · · ·+λnαn 6= 0 for all multi-indices of integers α 6= 0. The Birkhoff normal form says that under the non-resonance condition on λ, there is a formal symplectic tr...
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.

This article gives a simple treatment of the quantum Birkhoff normal form for semiclassical pseudo-differential operators with smooth coefficients. The normal form is applied to describe the discrete spectrum in a generalised non-degenerate potential well, yielding uniform estimates in the energy E. This permits a detailed study of the spectrum in various asymptotic regions of the parameters (E...

We prove that the Birkhoff map Ω for KdV constructed on H 0 (T) can be interpolated between H 0 (T) and L20(T). In particular, the symplectic phase space H 1/2 0 (T) can be described in terms of Birkhoff coordinates.
