ON ROOT SUBSYSTEMS AND INVOLUTIONS IN Sn
Published online by Cambridge University Press: 29 March 2010
Abstract
Given an involution z in W, where W is the symmetric group of degree n, we study the relation between the subsystems of a root system for W corresponding to certain decreasing subsequences of z and the two-sided Kazhdan–Lusztig cell of W containing z.
