Experimental study of tensor invariants of Hamiltonian systems [PDF]

open access: yesTheoretical and Applied Mechanics
Typically, one considers the problem of finding the minimum number of invariants of a dynamical system sufficient for integrability. It can be also assumed that there are invariants not related to integrability that describe other properties of the ...

Canonical transformations of linear Hamiltonian systems [PDF]

open access: yesE3S Web of Conferences
In this paper we consider the linear Hamiltonian systems of differential equations. We explore the normalization of a non-singular Hamiltonian matrix. We solve a system of matrix equations to find the generating function of the canonical transformation ...

Symmetry Preserving Discretization of the Hamiltonian Systems with Holonomic Constraints

open access: yesMathematics, 2021
Symmetry preserving difference schemes approximating equations of Hamiltonian systems are presented in this paper. For holonomic systems in the Hamiltonian framework, the symmetrical operators are obtained by solving the determining equations of Lie ...

Multiple Solutions for Generalized Asymptotical Linear Hamiltonian Systems Satisfying Bolza Boundary Conditions

open access: yesJournal of Applied Mathematics, 2013
This paper is devoted to multiple solutions of generalized asymptotical linear Hamiltonian systems satisfying Bolza boundary conditions. We classify the linear Hamiltonian systems by the index theory and obtain the existence and multiplicity of solutions

Dynamics of “leaking” Hamiltonian systems [PDF]

open access: yesPhysical Review E, 2002
In order to understand the dynamics in more detail, in particular for visualizing the space-filling unstable foliation of closed chaotic Hamiltonian systems, we propose to leak them up. The cutting out of a finite region of their phase space, the leak, through which escape is possible, leads to transient chaotic behavior of nearly all the trajectories.

Sampled Data Systems Passivity and Discrete Port-Hamiltonian Systems [PDF]

open access: yes, 2005
In this paper, we present a novel way to approach the interconnection of a continuous and a discrete time physical system. This is done in a way which preserves passivity of the coupled system independently of the sampling time T.

A new hierarchy of integrable system of 1+2 dimensions: from Newton's law to generalized Hamiltonian system. Part II

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
The Hamiltonian equation provides us an alternate description of the basic physical laws of motion, which is used to be described by Newton's law.

Existence of solutions for a class of second-order sublinear and linear Hamiltonian systems with impulsive effects

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
By using the saddle point theorem, some new existence theorems are obtained for second-order Hamiltonian systems with impulsive effects in the cases when the gradient of the nonlinearity grows sublinearly and grows linearly respectively.

Combining finite element space-discretizations with symplectic time-marching schemes for linear Hamiltonian systems

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
We provide a short introduction to the devising of a special type of methods for numerically approximating the solution of Hamiltonian partial differential equations.

Port-Hamiltonian Systems on Graphs [PDF]

open access: yesSIAM Journal on Control and Optimization, 2013
In this paper we present a unifying geometric and compositional framework for modeling complex physical network dynamics as port-Hamiltonian systems on open graphs. Basic idea is to associate with the incidence matrix of the graph a Dirac structure relating the flow and effort variables associated to the edges, internal vertices, as well as boundary ...
