INVERSIONS IN CLASSICAL WEYL GROUPS

Communications in Contemporary Mathematics, 2007
We introduce inversions for classical Weyl group elements and relate them, by counting, to the length function, root systems and Schubert cells in flag manifolds. Special inversions are those that only change signs in the Weyl groups of types Bn, Cnand Dn.

Displacement structure of group inverses

Numerical Linear Algebra with Applications, 2004
AbstractA matrix A is said to possess an UV‐displacement structure if rank(AU – VA) is small compared with the rank of A. Estimates for the rank AgV – UAg are presented, where Ag is the group inverse of A. Copyright © 2004 John Wiley & Sons, Ltd.
