Extended affine Weyl groups are the Weyl groups of root systems of a new class of Lie algebras called extended affine Lie algebras. In this paper we show that a ลฝ . reduced extended affine Weyl group is the homomorphic image of some indefinite KacแMoody Weyl group where the homomorphism and its kern
The quantum Weyl group \(\widetilde{U_{q}(g)}\) associated to a complex simple Lie algebra \(g\) consists of the quantum group \(U_{4}(g)\) with certain "quantum simple reflections" \(\bar{u}\), adjoined. Let \(k \tilde{W}\) be the group algebra of the standard covering \(\tilde{W}\) of the Weyl gro
