Poisson-Lie dynamical r-matrices from Dirac reduction
نویسنده
چکیده
The Dirac reduction technique used previously to obtain solutions of the classical dynamical Yang-Baxter equation on the dual of a Lie algebra is extended to the PoissonLie case and is shown to yield naturally certain dynamical r-matrices on the duals of Poisson-Lie groups found by Etingof, Enriquez and Marshall in math.QA/0403283.

Dirac submanifolds and Poisson involutions
Dirac submanifolds are a natural generalization in the Poisson category for symplectic submanifolds of a symplectic manifold. In a certain sense they correspond to symplectic subgroupoids of the symplectic groupoid of the given Poisson manifold. In particular, Dirac submanifolds arise as the stable locus of a Poisson involution. In this paper, we provide a general study for these submanifolds i...
متن کاملComparison of Poisson Structures and Poisson - Lie Dynamical
We construct a Poisson isomorphism between the formal Poisson manifolds g * and G * , where g is a finite dimensional quasitriangular Lie bialgebra. Here g * is equipped with its Lie-Poisson (or Kostant-Kirillov-Souriau) structure, and G * with its Poisson-Lie structure. We also quantize the Poisson-Lie dynamical r-matrices of Balog-Fehér-Palla.
متن کاملDynamical r-matrices and Poisson-Lie symmetries in the chiral WZNW model
We briefly review the possible Poisson structures on the chiral WZNW phase space and discuss the associated Poisson-Lie groupoids. Many interesting dynamical r-matrices appear naturally in this framework. Particular attention is paid to the special cases in which these r-matrices satisfy the classical dynamical Yang-Baxter equation or its PoissonLie variant. Talk presented at the Workshop on In...
متن کاملThe Chiral WZNW Phase Space and its Poisson-Lie Groupoid
The precise relationship between the arbitrary monodromy dependent 2-form appearing in the chiral WZNW symplectic form and the ‘exchange r-matrix’ that governs the corresponding Poisson brackets is established. Generalizing earlier results related to diagonal monodromy, the exchange r-matrices are shown to satisfy a new dynamical generalization of the classical modified Yang-Baxter equation, wh...
متن کاملQuasi-bialgebras and Dynamical R-matrices
We study the relationship between general dynamical Poisson groupoids and Lie quasi-bialgebras. For a class of Lie quasi-bialgebras G naturally compatible with a reductive decomposition , we extend the description of the moduli space of classical dynamical r-matrices of Etingof and Schiffmann. We construct, in each gauge orbit, an explicit analytic representative l can. We translate the notion ...
