Makhlouf, Formality and deformation of universal enveloping algebras, International Journal of Theoretical Physics, 47 2008 , 311—332. Poisson manifolds play a fundamental role in Hamiltonian dynamics, where they serve as phase spaces. We also introduce some notions and results of the theory of Lie algebroids including related Poisson structures on the dual bundle to the Lie algebroid. The special case of spacelike leafs evolving in time is studied.

Japan 61 2009 , no. The second paper is a combination of the results of the first paper and some related results by Selivanova, and somehow it appeared in the most prestigious Russian journal at that time. Stability of higher order singular points of Poisson manifolds and Lie algebroids. Lie-Sklyanin algebras corresponding to Poisson structures with trivial linearization are introduced and studied as well. One defines the U 2, 2 -invariant symplectic form on the twistor space T as d γ, where. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page.

On the other hand, it presents a comprehensive treatment of the normal form problem in Poisson geometry.

Using this toric characterization,and a new geometric approximation method in contrast to the fast convergence method , we show that any analytic integrable Hamiltonian resp. The collection of non-trivial associative algebras of a fixed dimension forms a projective variety. We present an algebraic framework for the computation of low-degree cohomology of a class of bigraded complexes which arise in Poisson geometry around pre symplectic leaves.

Poisson Structures and Their Normal Forms Progress in Mathematics Book Title :Poisson Structures and Their Normal Forms Progress in Mathematics Poisson manifolds play a fundamental role in Hamiltonian dynamics, where they serve as phase spaces. It presents such topics as asymptotic distributions of multiplicities, hierarchical patterns in multiplicity diagrams, lacunae, and the multiplicity diagrams of the rank 2 and rank 3 groups.

Our results solve a long-standing problem, and improve in a significant way previous results obtained by Rüssmann, Vey, Ito, Kappeler, Kodama, Nemethi, Bruno and Walcher. Even when it comes to classical results, the book gives new insights. But Nambu structures are dual to integrable differential forms, and as such they are very useful for the theory of singular foliations. Linearization of poisson structures -- 5. We sketch a geometric proof of Conn's linearizationtheorem for analytic Poisson structures witha semisimple linear part. Proceedings of the Steklov Institute of Mathematics. Even when it comes to classical results, the book gives new insights.

We also show that this framework can be applied to the more general context of Lie algebroids. In particular, we give a classification of linear Nambu structures also called finitedimensional Nambu-Lie algebras , and a linearization of Nambu tensors and co-Nambu forms, under the nondegeneracy condition.

Lie Theory 19 2009 , no. The proof is based on Reeb stability for singular foliation, Moser trick, and the geometric approximation method developed in our papers on normal forms of vector fields.

Unterberger, Supersymmetric extension of Schrodinger-invariance, Nuclear Physics B, vol. The usefulness of Nambu structures in physics is rather dubious. The authors take a novel approach, using the techniques of symplectic geometry.

After the publication of the book, there have been new interesting results about normal forms of Poisson structures, including: Crainic, Fernandes, Martinez geometric approach to linearization of Poisson structures and groupoids, Poisson structures of compact type , Marcut, Vorobiev normal forms in a neighborhood of a symplectic leaf , Stolovitch and Lohrmann analytic and Gevrey-class normal forms , Monnier, Miranda and myself rigidity of Hamiltonian actions , and so on.
