LEFT CELLS IN TYPE Bn WITH UNEQUAL PARAMETERS

چکیده

Kazhdan and Lusztig have shown that the partition of the symmetric group Sn into left cells is given by the Robinson–Schensted correspondence. The aim of this paper is to provide a similar description of the left cells in type Bn for a special class of choices of unequal parameters. This is based on a generalization of the Robinson–Schensted correspondence in type Bn. We provide an explicit description of the left cell representations and show that they are irreducible and constructible.

Constructible Characters, Leading Coefficients and Left Cells for Finite Coxeter Groups with Unequal Parameters

Following Lusztig, we investigate constructible characters, leading coefficients and left cells for a finite Coxeter group W in the case of unequal parameters. We obtain explicit results for W of type F4, Bn and I2(m) (m even) which support Lusztig’s conjecture that known results about left cells in the equal parameter case should remain valid in the case of unequal parameters.

2 00 5 LUSZTIG ’ S a - FUNCTION IN TYPE B n IN THE ASYMPTOTIC CASE

In this paper, we study Lusztig's a-function for a Coxeter group with unequal parameters. We determine that function explicitly in the " asymptotic case " in type Bn, where the left cells have been determined in terms of a generalized Robinson–Schensted correspondence by Bonnafé and the second author. As a consequence, we can also show that all of Lusztig's conjectural properties (P1)–(P15) hol...

Computing Kazhdan–lusztig Cells for Unequal Parameters

Following Lusztig, we consider a Coxeter group W together with a weight function L. This gives rise to the pre-order relation 6L and the corresponding partition of W into left cells. We introduce an equivalence relation on weight functions such that, in particular, 6L is constant on equivalent classes. We shall work this out explicitly for W of type F4 and check that several of Lusztig’s conjec...

Density functional explorations of quadrupole coupling constants for BN, BP, AlN, and AlP graphene–like structures

Stabilizations and atomic level quadrupole coupling constant (CQ) properties have been investigated for graphene–like monolayers (G–monolayers) of boron nitride (BN), boron phosphide (BP), aluminum nitride (AlN), and aluminum phosphide (AlP) structures. To this aim, density functional theory (DFT) calculations have been performed to optimize the model structures and also to evaluate the CQ para...
