Symplectic integration of Hamiltonian systems using polynomial maps [PDF]

open access: yesPhysics Letters A, 2001
In order to perform numerical studies of long-term stability in nonlinear Hamiltonian systems, one needs a numerical integration algorithm which is symplectic. Further, this algorithm should be fast and accurate. In this paper, we propose such a symplectic integration algorithm using polynomial map refactorization of the symplectic map representing the

Polynomial and rational integrability of polynomial Hamiltonian systems

open access: yesElectronic Journal of Differential Equations, 2012
Within the class of canonical polynomial Hamiltonian systems anti-symmetric under phase-space involutions, we generalize some results on the existence of Darboux polynomial and rational first integrals for "kinetic plus potential" systems to general ...

Effective descriptions of bosonic systems can be considered complete [PDF]

open access: yesNature Communications
Bosonic statistics give rise to remarkable phenomena, from the Hong–Ou–Mandel effect to Bose–Einstein condensation, with applications spanning fundamental science to quantum technologies. Modeling bosonic systems relies heavily on effective descriptions:

Darboux polynomials and first integrals of natural polynomial Hamiltonian systems [PDF]

open access: yesPhysics Letters A, 2004
We show that for a natural polynomial Hamiltonian system the existence of a single Darboux polynomial (a partial polynomial first integral) is equivalent to the existence of an additional first integral functionally independent with the Hamiltonian function.

Limit Cycles of Polynomially Integrable Piecewise Differential Systems

open access: yesAxioms, 2023
In this paper, we study how many algebraic limit cycles have the discontinuous piecewise linear differential systems separated by a straight line, with polynomial first integrals on both sides.

Limit Cycles of a Class of Perturbed Differential Systems via the First-Order Averaging Method

open access: yesComplexity, 2021
By means of the averaging method of the first order, we introduce the maximum number of limit cycles which can be bifurcated from the periodic orbits of a Hamiltonian system.

Linearizability of planar polynomial Hamiltonian systems

open access: yesNonlinear Analysis: Real World Applications, 2022
Isochronicity and linearizability of two-dimensional polynomial Hamiltonian systems are revisited and new results are presented. We give a new computational procedure to obtain the necessary and sufficient conditions for the linearization of a polynomial system.

On integrals, Hamiltonian and metriplectic formulations of polynomial systems in 3D [PDF]

open access: yesTheoretical and Applied Mechanics, 2017
The first integrals of the reduced three-wave interaction problem, the Rabinovich system, the Hindmarsh-Rose model, and the Oregonator model are derived using the method of Darboux polynomials.

Solving systems of Boolean multivariate equations with quantum annealing

open access: yesPhysical Review Research, 2022
Polynomial systems over the binary field have important applications, especially in symmetric and asymmetric cryptanalysis, multivariate-based postquantum cryptography, coding theory, and computer algebra.

Complete commutative subalgebras in polynomial poisson algebras: A proof of the Mischenko-Fomenko conjecture [PDF]

open access: yesTheoretical and Applied Mechanics, 2016
The Mishchenko-Fomenko conjecture says that for each real or complex finite-dimensional Lie algebra g there exists a complete set of commuting polynomials on its dual space g*.
