A remarkable connection between Yangians and finite W-algebras
نویسندگان
چکیده
For a large class of finite W algebras, the defining relations of a Yangian are proved to be satisfied. Therefore such finite W algebras appear as realisations of Yangians. This result is useful to determine properties of such W algebra representations. Talk presented by P. Sorba at NEEDS’97 (Kolymbari, Creta, June 1997), VIII Regional Conference on Math. Phys.

Twisted Yangians and finite W-algebras
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.
متن کاملTwisted Yangians, Twisted Quantum Loop Algebras and Affine Hecke Algebras of Type Bc
We study twisted Yangians of type AIII which have appeared in the literature under the name of reflection algebras. They admit q-versions which are new twisted quantum loop algebras. We explain how these can be defined equivalently either via the reflection equation or as coideal subalgebras of Yangians of gln (resp. of quantum loop algebras of gln). The connection with affine Hecke algebras of...
متن کاملTwisted 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 کاملAffine Yangians and deformed double current algebras in type A
We study the structure of Yangians of affine type and deformed double current algebras, which are deformations of the enveloping algebras of matrix W1+∞-algebras. We prove that they admit a PBWtype basis, establish a connection (limit construction) between these two types of algebras and toroidal quantum algebras, and we give three equivalent definitions of deformed double current algebras. We ...
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...
