| Mar 20, 2021 at 10:43 | comment | added | AThomas | In some situations, the distinction between "integral" and "non-integral" is linked to the distinction between Hecke algebras coming from a Weyl group or from a Coxeter group (for example for the coefficients of Schur elements). Is this true for the values of irreducible characters on the KL basis? The example you give, a dihedral group, is a Coxeter group which is not a Weyl group. | |
