Unsaturated triglyceride oil (sunflower) was obtained from commercial sources. It was
epoxidized and characterized by chemical and spectroscopic methods. The thermo …

The main object considered in the paper is the integrable Hamiltonian system. Starting from
classical papers written more than 200 years ago, integrable Hamiltonian systems were …

In this thesis we study the problem of classification of symplectic structures in a
neighbourhood of a singular compact orbit of a completely integrable system on a …

Nous présentons une classification des orbites coadjointes génériques pour les groupes de
symplectomorphismes et de difféomorphismes hamiltoniens des surfaces fermées …

The main purpose of this paper is to present in a unified approach to different results
concerning group actions and integrable systems in symplectic, Poisson and contact …

We prove, under some generic assumptions, that the semiclassical spectrum modulo O (ћ 2)
of a one-dimensional pseudodifferential operator completely determines the symplectic …

Dans cette thèse, nous prouvons des résultats de théorie spectrale, directe et inverse, dans
la limite semi-classique, pour les opérateurs de Toeplitz autoadjoints sur les surfaces. Pour …

In this thesis, we classify generic coadjoint orbits for the action of symplectic (equivalently,
area-preserving) diffeomorphisms of compact symplectic surfaces with or without boundary …

This article is a survey of classical and quantum completely integrable systems from the
viewpoint of local``phase space''analysis. It advocates the use of normal forms and shows …
