Hecke group algebras as degenerate affine Hecke algebras
The Hecke group algebra H W̊ of a finite Coxeter group W̊ , as introduced by the first and last author, is obtained from W̊ by gluing appropriately its 0-Hecke algebra and its group algebra. In this paper, we give an equivalent alternative construction in the case when W̊ is the classical Weyl group associated to an affine Weyl group W . Namely, we prove that, for q not a root of unity, H W̊ is the ...
متن کاملAffine Hecke algebras, cyclotomic Hecke algebras and Clifford theory
We show that the Young tableaux theory and constructions of the irreducible representations of the Weyl groups of type A, B and D, Iwahori-Hecke algebras of types A, B, and D, the complex reflection groups G(r, p, n) and the corresponding cyclotomic Hecke algebras Hr,p,n, can be obtained, in all cases, from the affine Hecke algebra of type A. The Young tableaux theory was extended to affine Hec...

متن کاملAffine Hecke algebras and the Schubert calculus
Using a combinatorial approach which avoids geometry, this paper studies the ring structure of KT (G/B), the T -equivariant K-theory of the (generalized) flag variety G/B. Here, the data G ⊇ B ⊇ T is a complex reductive algebraic group (or symmetrizable Kac-Moody group)G, a Borel subgroup B, and a maximal torus T , and KT (G/B) is the Grothendieck group of T -equivariant coherent sheaves on G/B...
