W-superalgebras as Truncations of Super-yangians
نویسندگان
چکیده
We show that some finite W-superalgebras based on gl(M |N) are truncation of the super-Yangian Y (gl(M |N)). In the same way, we prove that finite W-superalgebras based on osp(M |2n) are truncation of the twisted super-Yangians Y (gl(M |2n)) +. Using this homomorphism, we present these W-superalgebras in an R-matrix formalism, and we classify their finite-dimensional irreducible representations.

Representations of super Yangian
We present in detail the classification of the finite dimensional irreducible representations of the super Yangian associated with the Lie superalgebra gl(1|1). 1 Introduction Many new algebraic structures were discovered in the study of soluble models in statistical mechanics and quantum field theory. Amongst them the quantum groups[1][2] and Yangians[3] are particularly interesting. The forme...
متن کاملYangians of Lie Superalgebras
This thesis is concerned with extending some well-known results about the Yangians Y (glN) and Y (slN) to the case of super-Yangians. First we produce a new presentation of the Yangian Y (glm|n), using the Gauss decomposition of a matrix with non-commuting entries. Then, by writing the quantum Berezinian in terms of generators from the new presentation we prove that its coefficients generate th...
متن کاملUniversal Central Extension of Current Superalgebras
Representation as well as central extension are two of the most important concepts in the theory of Lie (super)algebras. Apart from the interest of mathematicians, the attention of physicist are also drawn to these two subjects because of the significant amount of their applications in Physics. In fact for physicists, the study of projective representations of Lie (super)algebras are very impo...

We obtain Drinfel ′ d's realization of quantum affine superalgebra U q (gl(1|1)) based on the super version of RS construction method and Gauss decomposition. How to construct quantum algebras (including quantum affine algebras and Yangians) is a important problem in mathematics physics. After Drinfel ′ d [1] and Jimbo [3, 4] independently discovered that the universal enveloping algebra U(g) o...
متن کاملOn Super RS Algebra and Drinfeld Realization of Quantum Affine Superalgebras
We describe the realization of the super Reshetikhin-Semenov-Tian-Shansky (RS) algebra in quantum affine superalgebras, thus generalizing the approach of Frenkel-Reshetikhin to the supersymmetric (and twisted) case. The algebraic homomorphism between the super RS algebra and the Drinfeld current realization of quantum affine superalgebras is established by using the Gauss decomposition techniqu...
