Involution centralizers in matrix group algorithms

Its ,centralizer, C G(t) is the subgroup of elements which commute with it, so C G(t) = {g ∈ G | tg = gt}. It has long been accepted in abstract group theory that the way to study simple groups is via their involution centralizers. But this orthodoxy has been slow to ﬁlter through into computational group theory. Part of the purpose of this talk

THE CENTRALIZER OF A SUBGROUP IN A GROUP ALGEBRA

THE CENTRALIZER OF A SUBGROUP IN A GROUP ALGEBRA SUSANNE DANZ, HARALD ELLERS, AND JOHN MURRAY If Ris a commutative ring, Gis a nite group, and His a subgroup of G, then the centralizer algebra RGH is the set of all elements of RGthat commute with all elements of H. The algebra RGH is a Hecke algebra in the sense that it is isomorphic to End RH G(RG) = End

CiteSeerX — Matrices connected with Brauer's centralizer ...

In a 1989 paper [HW1], Hanlon and Wales showed that the algebra structure of the Brauer Centralizer Algebra A (x) f is completely determined by the ranks of certain combinatorially defined square matrices Z =¯ , whose entries are polynomials in the parameter x.

ON CENTRALIZERS OF BANACH ALGEBRAS Introduction

centralizer, if and only if ’(a) = a’(1) = ’(1)afor each a2A. Clearly, each (right, left) ,centralizer, is a (right, left) Jordan ,centralizer,. The converse is, in general, not true (see Example 2.6). It is natural and interesting to nd some conditions under which a (right, left) Jordan ,centralizer, is a (right, left) ,centralizer,.

ON CERTAIN CLASSES OF ALGEBRAS IN WHICH CENTRALIZERS …

The, centralizer, of an element x 2A is the set C A(x) = fy 2A jxy = yx = 0 for all y 2Ag: Following [3] we call A a, CL-algebra, if every, centralizer, in A is an ideal of A. We will say that elements x;y 2A have commutative bonding (CB) if xy = 0 implies that (xz)y = 0 for all z 2A. The, algebra, A is then deﬁned to be a, CB-algebra, if every pair
