BRST operators for W algebras
A. P. Isaev, S. O. Krivonos, O. V. Ogievetsky
The study of quantum Lie algebras motivates a use of non-canonical ghosts and anti-ghosts for non-linear algebras, like W-algebras. This leads, for the W_3 and W_3^(2) algebras, to…

Baxterized Solutions of Reflection Equation and Integrable Chain Models
A. P. Isaev, O. V. Ogievetsky
Non-polynomial Baxterized solutions of reflection equations associated with affine Hecke and affine Birman-Murakami-Wenzl algebras are found. Relations to integrable spin chain mod…
