On the Relation of Extended Affine Weyl
✍ Saeid Azam 📂 Article 📅 1999 🏛 Elsevier Science 🌐 English ⚖ 125 KB

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 Ž . reduced extended affine Weyl group is the homomorphic image of some indefinite Kac᎐Moody Weyl group where the homomorphism and its kern
