"A Unified construction of Coxeter group representations"

abstract: We present a unified construction of representations for
Coxeter groups and their Iwahori-Hecke algebras.
The construction is carried out by a natural assumption on the
representation matrices. For simply laced Coxeter groups, this assumption 
turns out to give explicit simple representation matrices, generalizing 
the Young Orthogonal Form. For the symmetric groups the resulting 
representations include the irreducible ones, as in Kazhdan-Lusztig 
theory.
