Stabilization of Hamiltonian systems [PDF]

open access: greenNonlinear Analysis: Theory, Methods & Applications, 1986
1. HAMILTONIAN SYSTEMS IN THIS paper we will be concerned with the stabilization by feedback of Hamiltonian systems. In order to facilitate our discussions (especially when applying Lyapunov’s second method) we will restrict ourselves to a particular, although natural, subclass of Hamiltonian systems given in the following way [l].

Ergodicity in Hamiltonian systems [PDF]

open access: green, 1992
We discuss the Sinai method of proving ergodicity of a discontinuous Hamiltonian system with (non-uniform) hyperbolic behavior.

Identifications of the coefficients of the Taylor expansion (second order) of periodic non-collision solutions for the perturbed planar Keplerian Hamiltonian system

open access: yesAIMS Mathematics, 2023
The discussion of disordered Keplerian Hamiltonian systems in our previously published study, which we verified, is expanded upon in this article. The collision semicircular orbit, and at least one other symmetric orbit is mentioned in this article.

Real Hamiltonian forms of Hamiltonian systems [PDF]

open access: yesThe European Physical Journal B, 2004
We introduce the notion of a real form of a Hamiltonian dynamical system in analogy with the notion of real forms for simple Lie algebras. This is done by restricting the complexified initial dynamical system to the fixed point set of a given involution. The resulting subspace is isomorphic (but not symplectomorphic) to the initial phase space. Thus to

Contact Hamiltonian systems [PDF]

open access: yesJournal of Mathematical Physics, 2019
In this paper, we study Hamiltonian systems on contact manifolds, which is an appropriate scenario to discuss dissipative systems. We show how the dissipative dynamics can be interpreted as a Legendrian submanifold, and also prove a coisotropic reduction theorem similar to the one in symplectic mechanics; as a consequence, we get a method to reduce the

Brake orbits with minimal period estimates of first-order variant subquadratic Hamiltonian systems

open access: yesElectronic Research Archive, 2022
Under a generalized subquadratic growth condition, brake orbits are guaranteed via the homological link theorem. Moreover, the minimal period estimate is given by Morse index estimate and $ L_{0} $-index estimate.

ON THE SYMMETRIES OF HAMILTONIAN SYSTEMS [PDF]

open access: yesInternational Journal of Modern Physics A, 1995
In this paper we show how the well-known local symmetries of Lagrangian systems, and in particular the diffeomorphism invariance, emerge in the Hamiltonian formulation. We show that only the constraints which are linear in the momenta generate transformations which correspond to symmetries of the corresponding Lagrangian system.

An efficient linearly-implicit energy-preserving scheme with fast solver for the fractional nonlinear wave equation

open access: yesAIMS Mathematics, 2023
The paper considers the Hamiltonian structure and develops efficient energy-preserving schemes for the nonlinear wave equation with a fractional Laplacian operator. To this end, we first derive the Hamiltonian form of the equation by using the fractional

Modeling and Analysis of a Three-Terminal-Memristor-Based Conservative Chaotic System

open access: yesEntropy, 2021
In this paper, a three-terminal memristor is constructed and studied through changing dual-port output instead of one-port. A new conservative memristor-based chaotic system is built by embedding this three-terminal memristor into a newly proposed four ...

Sections of Hamiltonian Systems [PDF]

open access: yesRegular and Chaotic Dynamics, 2021
A section of a Hamiltonian system is a hypersurface in the phase space of the system, usually representing a set of one-sided constraints (e.g. a boundary, an obstacle or a set of admissible states). In this paper we give local classification results for all typical singularities of sections of regular (non-singular) Hamiltonian systems, a problem ...
