Drinfeld Basis And a Nonclassical Free Boson Representation of Twisted Quantum Affine Superalgebra Uq[osp(2|2)(2)]
Wen-Li Yang, Yao-Zhong Zhang
Abstract
We derive from the super RS algebra the Drinfeld basis of the twisted quantum affine superalgebra Uq[osp(2|2)(2)] by means of the Gauss decomposition technique. We explicitly construct a nonclassical level-one representation of Uq[osp(2|2)(2)] in terms of two q-deformed free boson fields.
