Twisted Yangians and finite W-algebras

چکیده
We construct an explicit set of generators for the finite W -algebras associated to nilpotent matrices in the symplectic or orthogonal Lie algebras whose Jordan blocks are all of the same size. We use these generators to show that such finite W -algebras are quotients of twisted Yangians.

Twisted Yangians and folded W-algebras
We show that the truncation of twisted Yangians are isomorphic to finite Walgebras based on orthogonal or symplectic algebras. This isomorphism allows us to classify all the finite dimensional irreducible representations of the quoted W-algebras. We also give an R-matrix for these W-algebras, and determine their center. math.QA/0012182 LAPTH-824/00 December 2000 [email protected] UMR 5108 d...
متن کاملDrinfeld J Presentation of Twisted Yangians
We present a quantization of a Lie coideal structure for twisted half-loop algebras of finite-dimensional simple complex Lie algebras. We obtain algebra closure relations of twisted Yangians in Drinfeld J presentation for all symmetric pairs of simple Lie algebras and for simple twisted even half-loop Lie algebras. We provide the explicit form of the closure relations for twisted Yangians in Dr...
متن کاملFinite-dimensional Irreducible Representations of Twisted Yangians
We study quantized enveloping algebras called twisted Yangians. They are analogues of the Yangian Y(gl(N)) for the classical Lie algebras of B, C, and D series. The twisted Yangians are subalgebras in Y(gl(N)) and coideals with respect to the coproduct in Y(gl(N)). We give a complete description of their finite-dimensional irreducible representations. Every such representation is highest weight...
متن کاملSe p 20 09 Representations of twisted q - Yangians by Lucy Gow and
The twisted q-Yangians are coideal subalgebras of the quantum affine algebra associated with glN . We prove a classification theorem for finite-dimensional irreducible representations of the twisted q-Yangians associated with the symplectic Lie algebras sp2n. The representations are parameterized by their highest weights or by their Drinfeld polynomials. In the simplest case of sp2 we give an e...
