Francis, Andrew R. and Wynn, Henry P. (2014) Subgroup majorization. Linear Algebra and Its Applications, 444 . pp. 53-66. ISSN 0024-3795
The extension of majorization (also called the rearrangement ordering), to more general groups than the symmetric (permutation) group, is referred to as G-majorization. There are strong results in the case that G is a reflection group and this paper builds on this theory in the direction of subgroups, normal subgroups, quotient groups and extensions. The implications for fundamental cones and order-preserving functions are studied. The main example considered is the hyperoctahedral group, which, acting on a vector in ℝn, permutes and changes the signs of components. Crown Copyright © 2013 Published by Elsevier Inc.
