arXiv:1009.1933 · doi:10.1016/j.geomphys.2010.06.014
Abstract
In this article, we give an explicit formula for the universal weight function of the quantum twisted affine algebra . The calculations use the technique of projecting products of Drinfeld currents onto the intersection of Borel subalgebras of different types.
