Pre-canonical bases on affine Hecke algebras

چکیده
For any affine Weyl group, we introduce the pre-canonical bases. They are a set of bases {Ni}1?i?m+1 (where m is height highest root) spherical Hecke algebra that interpolates between standard basis N1 and canonical Nm+1. The expansion Ni+1 in terms Ni many cases very simple conjecture type A it positive.

Induced representations of affine Hecke algebras and canonical bases of quantum groups
A criterion of irreducibility for induction products of evaluation modules of type A affine Hecke algebras is given. It is derived from multiplicative properties of the canonical basis of a quantum deformation of the Bernstein-Zelevinsky ring.
متن کاملHecke 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 کاملNotes on Affine Canonical and Monomial Bases
We investigate the affine canonical basis ([L2]) and the monomial basis constructed in [LXZ] in Lusztig’s geometric setting. We show that the transition matrix between the two bases is upper triangular with 1’s in the diagonal and coefficients in the upper diagonal entries in Z≥0[v, v ]. As a consequence, we show that part of the monomial basis elements give rise to resolutions of support varie...
