Integrable Chain Model with Additional Staggered Model Parameter
D. Arnaudon, R. Poghossian, A. Sedrakyan +1
The generalization of the Yang-Baxter equations (YBE) in the presence of Z_2 grading along both chain and time directions is presented. The XXZ model with staggered disposition alo…
A remarkable connection between Yangians and finite W-algebras
E. Ragoucy, P. Sorba
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 re…
Dictionary on Lie Superalgebras
L. Frappat, A. Sciarrino, P. Sorba
The main definitions and properties of Lie superalgebras are proposed a la facon de a short dictionary, the different items following the alphabetical order. The main topics deal w…
(SUPER) W Algebras from Non Abelian (SUPER) Toda Theories
L. Frappat, E. Ragoucy, P. Sorba
A classification of (super) algebras arising from non Abelian Toda and super Toda theories is presented. This classification is based on the or sub(super)alg…
