Discrete embeddings for Lagrangian and Hamiltonian systems [PDF]
The general topic of the present paper is to study the conservation for some structural property of a given problem when discretising this problem. Precisely we are interested with Lagrangian or Hamiltonian structures and thus with variational problems ...

Lyapunov inequalities for discrete linear Hamiltonian systems
The authors study the discrete system \[ \begin{aligned} x(t+1)-x(t)&=a(t)x(t+1)+b(t)u(t)\\ u(t+1)-u(t)&=-c(t)x(t+1)-a(t)u(t). \end{aligned}\tag{1} \] They derive some Lyapunov type inequalities from (1). They use these inequalities to derive a disconjugacy criterion. Then they study the stability of (1) when the coefficients \(a(t)\), \(b(t)\) and \(c(

Subharmonics with Minimal Periods for Convex Discrete Hamiltonian Systems [PDF]
We consider the subharmonics with minimal periods for convex discrete Hamiltonian systems. By using variational methods and dual functional, we obtain that the system has a -periodic solution for each positive integer , and solution of system has minimal

DISCRETE LEFT-DEFINITE HAMILTONIAN SYSTEMS
Summary: In this paper we consider an even-dimensional discrete Hamiltonian system on the set of nonnegative integers in the left-definite form. Using the inertia indices of the hermitian form related with the solutions of the equation we construct some maximal subspaces of the solution space.

Sampled data systems passivity and discrete port-Hamiltonian systems [PDF]
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. This strategy can be used both in the field of telemanipulation, for the implementation of a passive master/slave system on

Homoclinic Orbits for a Class of Noncoercive Discrete Hamiltonian Systems
A class of first-order noncoercive discrete Hamiltonian systems are considered. Based on a generalized mountain pass theorem, some existence results of homoclinic orbits are obtained when the discrete Hamiltonian system is not periodical and need not ...

Weyl-Titchmarsh Theory for Hamiltonian Dynamic Systems
We establish the Weyl-Titchmarsh theory for singular linear Hamiltonian dynamic systems on a time scale 𝕋, which allows one to treat both continuous and discrete linear Hamiltonian systems as special cases for 𝕋=ℝ and 𝕋=ℤ within ...
