On Critical Behaviour in Systems of Hamiltonian Partial Differential Equations [PDF]
We study the critical behaviour of solutions to weakly dispersive Hamiltonian systems considered as perturbations of elliptic and hyperbolic systems of hydrodynamic type with two components.

QUANTUM BI-HAMILTONIAN SYSTEMS [PDF]
We define quantum bi-Hamiltonian systems, by analogy with the classical case, as derivations in operator algebras which are inner derivations with respect to two compatible associative structures. We find such structures by means of the associative version of Nijenhuis tensors. Explicit examples, e.g. for the harmonic oscillator, are given.

A Finite Dimensional Approximation of the shallow water Equations: The port-Hamiltonian Approach [PDF]
We look into the problem of approximating a distributed parameter port-Hamiltonian system which is represented by a non-constant Stokes-Dirac structure.

On First Integrals of Hamiltonian System with Holonomic Hamiltonian
In this study, the solution of the Hamilton-Jacobi equation (HJE) with holonomic Hamiltonian is investigated in terms of the first integrals of the corresponding Hamiltonian system. Holonomic functions are related to a specific type of partial differential equations called Pfaffian systems, whose solution space can be regarded as a finite-dimensional ...

Symmetry and Resonance in Hamiltonian Systems [PDF]
The authors consider a two-degree-of-freedom Hamiltonian \[ H(p_1,q_1,p_2,q_2)= \textstyle{{1\over 2}} \omega_1(p^2_1+ q^2_1)+ \textstyle{{1\over 2}} \omega_2(p^2_2+ q^2_2)+ H_3+ H_4+\cdots, \] where \(H_k\) \((k\geq 3)\) are homogeneous polynomials of degree \(k\).

Hamiltonian systems with constraints
We study the classical Hamiltonian of constraints systems. We will start by defining a Lagrangian function that defines a dynamical system with constraints and then we will derive the corresponding Hamiltonian formulation through a Legendre ...

Existence and multiplicity of homoclinic solutions for a second-order Hamiltonian system
In this paper, we find new conditions to ensure the existence of one nontrivial homoclinic solution and also infinitely many homoclinic solutions for the second order Hamiltonian system $$ \ddot{u}-a(t)|u|^{p-2}u+\nabla W(t,u)=0,\qquad t\in \mathbb{R}, $

Stabilization of Hamiltonian systems [PDF]
Stabilization of Hamiltonian control systems is considered, using the first and the second Lypunov method. As the main result sufficient conditions are stated for an analytic Hamiltonian control system to be made locally asymptotically stable by an extended output feedback i.e. both the outputs and their derivatives are fed back.
