Smooth normal forms for integrable hamiltonian systems near a focus-focus singularity.. San Vu Ngoc,

Herman had obtained by such a method a first version of the stability result, but without being able to reach the exponents (1.2) of Theorem A; this is why we’ll have to make do

This system was shown to act as an effective receptor for neutral electron acceptors and the complexation ability of clip 1 toward the neutral guest, such as F 4 -TCNQ, was evaluated

Then, after giving some exemples of Hamilto- nian PDEs, we present an abstract Birkhoff normal form theorem in infinite dimension and discuss the dynamical consequences for

By construction, this function Ψ p is smooth (or real analytic) if ψ p is smooth (or real analytic) and depends smoothly or analytically on the parameters if ψ p does so.. After

In this paper we are concerned with the normal form of a completely integrable Hamiltonian system near an equilibrium point.. hn are

We establish a priori Lipschitz estimates for unbounded solutions of second- order Hamilton-Jacobi equations in R N in presence of an Ornstein-Uhlenbeck drift.. We generalize

Le marketing stratégique porte sur la façon dont l’entreprise agit vis-à-vis de sa concurrence ; sur quel marché ou segment de marché, avec quel produit (imitation,

This article reviews the Birkho¤-Gustavson normal form theorem (BGNF) near an equilibrium point of a quantum Hamiltonian.. The BGNF process is thereafter used to investigate

Notice that a Hamiltonian in nth normal form is also in renormalized form up to order n, as it was the case for dynamical systems (vector fields,. formal power

la jonction, les petits côtés de la transition (côté guide d’onde rectangulaire) étant arrondis et ne. coïncidant pas ainsi avec les petits côtés du

C'est l'élargissement des gammes qui, en répondant aux attentes spécifiques des consommateurs, a permis le développement : du savon de ménage aux produits

As an application, we establish that the optimal value of a class of nonconvex polynomial optimization problems with suitable sign structure (or more explicitly, with

Restricted to such a generic coadjoint orbit, the Euler-Poisson equations are Hamiltonian relative to the orbit symplectic form and have the total energy H conserved.. To be
