A condition for an area-preserving mapping to be in the Engel’s form

Journal of Mathematical Physics, 2000
We establish explicit expressions of restrictions on the coefficients of nonlinear terms in a two-dimensional area-preserving polynomial map imposed by the property of area preserving. We also establish a necessary and sufficient condition for a two-dimensional area-preserving generic polynomial map to be in the Engel’s form.

Perturbations of Area Preserving Mappings

1972

NONTWIST AREA PRESERVING MAPS WITH REVERSING SYMMETRY GROUP

International Journal of Bifurcation and Chaos, 2001
The aim of this paper is to give a theoretical explanation of the rich phenomenology exhibited by nontwist mappings of the cylinder, in numerical experiments reported in [del-Castillo et al., 1996; Howard & Humpherys, 1995], and to give new insights on the dynamics of nontwist standard-like maps.

Bifurcations in 2D Area-Preserving Mappings

1984
We consider a class of two-dimensional area-preserving mappings of $$T:{x_{n + 1}} = 2h\left( {{x_n}} \right) - {y_n};{y_{n + 1}} = {x_n}.$$ (1)

Quantum levels of area-preserving maps

Physica D: Nonlinear Phenomena, 1988
A method is given for quantizing volume-preserving polynomial mappings, using Heisenberg's matrix formulation of quantum mechanics. The energy levels of the linear map are obtained exactly and those of the quadratic, nonintegrable, Hénon map approximately and numerically.

Introduction to the dynamics of area–preserving maps

AIP Conference Proceedings, 1987
Confinement of charged particles in electromagnetic fields, plasma heating, intermolecular dynamics, etc. can all be modeled by Hamiltonian systems dq/dt=∂H(q,p,t)/∂p dp/dt=−∂H(q,p,t)/∂q where q and p are n−dimensional, H is the Hamiltonian, n the number of degrees of freedom, and (p,q) is the phase space. These lectures are structured to describe such
