Bicrossproduct Structure of Affine Quantum Groups
S. Majid
Abstract
We show that the affine quantum group Uq(sl2) is isomorphic to a bicrossproduct central extension C Zχ Uq(Lsl2) of the quantum loop group Uq(Lsl2) by a quantum cocycle χ, which we construct. We prove the same result for Uq(g) in R-matrix form.
