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.

Group inverse sampling: An economical approach to inverse sampling

Environmetrics, 2017
Inverse sampling is an adaptive design in the sense that the final sampling effort during a search for rare events will depend on what is found during the survey. Conventional inverse sampling (CIS) designs successively select individual sampling units to find, for example, the kth rare event.

The Continuity of Inverse in Groups

Moscow University Mathematics Bulletin, 2022
This article is a contribution to the question under which conditions a paratopological group is a topological group. For that the author introduces the concept of a \(\Delta\)-Baire space. A topological space \(X\) is a \(\Delta\)-Baire space if for every set \(P\subseteq X\times X\) containing the diagonal \(\Delta:=\{(x,x):x\in X\}\) and having the ...

Individuals, Groups and Inverse Discrimination

Analysis, 1973
M ANY morally sensitive people find themselves faced with the following dilemma. On the one hand, they are persuaded by the argument that if being black, e.g., is morally irrelevant, then it is morally irrelevant and no more justifies favourable inverse discrimination than it justifies unfavourable discrimination.

Inverse semigroups through groups

International Journal of Mathematical Education in Science and Technology, 1990
In most introductory abstract algebra courses the topics covered are groups, rings and fields. In recent years, semigroups have been included due to their value in certain areas of computer science. However, after a few examples of familiar semigroups, the subject is forgotten and concentration is placed on developing the group structure. In this paper
