The weight function for the quantum affine algebra Uq(A_2^(2))

Journal of Geometry and Physics. 2010. Vol. 60. No. 11. P. 1833-1851.
Khoroshkin S. M., Shapiro A.

In this article, we give an explicit formula for the universal weight function of the quantum twisted affine algebra Uq(A(2)2 ). The calculations use the technique of projecting products of Drinfeld currents onto the intersection of Borel subalgebras of different types.
