Compatible Feigin–Odesskii Poisson brackets

نویسندگان

چکیده

We prove that several Feigin–Odesskii Poisson brackets associated with normal elliptic curves in $${{\mathbb {P}}}^n$$ are compatible if and only they contained a scroll or Veronese surface {P}}}^5$$ (with an exception of one case when $$n=3$$ ). In the we determine quartic corresponding to Schouten bracket two (non-compatible) $$E_1$$ $$E_2$$ .

Compatible nonlocal Poisson brackets

In the present work, the integrable bi-Hamiltonian hierarchies related to compatible nonlocal Poisson brackets of hydrodynamic type are effectively constructed. For achieving this aim, first of all, the problem on the canonical form of a special type for compatible nonlocal Poisson brackets of hydrodynamic type is solved. The compatible pairs of nonlocal Poisson brackets of hydrodynamic type ha...

An operadic approach to deformation quantization of compatible Poisson brackets

An analogue of the Livernet–Loday operad for two compatible brackets, which is a flat deformation of the bi-Hamiltonian operad is constructed. The Livernet–Loday operad can be used to define ⋆-products and deformation quantization for Poisson structures. The constructed operad is used in the same way, introducing a definition of operadic deformation quantization of compatible Poisson structures...

Integrability of Poisson Brackets

We show that various notions of integrability for Poisson brackets are all equivalent, and we give the precise obstructions to integrating Poisson manifolds. We describe the integration as a symplectic quotient, in the spirit of the Poisson sigma-model of Cattaneo and Felder. For regular Poisson manifolds we express the obstructions in terms of variations of symplectic areas. As an application ...

Poisson brackets in Hydrodynamics

This paper investigates different Poisson structures that have been proposed to give a Hamiltonian formulation to evolution equations issued from fluid mechanics. Our aim is to explore the main brackets which have been proposed and to discuss the difficulties which arise when one tries to give a rigorous meaning to these brackets. Our main interest is in the definition of a valid and usable bra...
