Commutator - Wikipedia

Group theory. The ,commutator, of two elements, g and h, of a group G, is the element [g, h] = g −1 h −1 gh.This element is equal to the group's identity if and only if g and h commute (from the ,definition, gh = hg [g, h] , being [g, h] equal to the identity if and only if gh = hg).. The set of all commutators of a group is not in general closed under the group operation, but the subgroup of ...

But the detailed structure theory involving centralizers of tori and parabolics was first undertaken over a general field of ,definition, by Borel and Tits in their foundational 1965 paper here. The relevant material (applicable whenever $G$ is $k$-isotropic) is contained in sections 3 and 4, with a fairly explicit general statement in Theorem 4.15.

5/1/2000, · Our definition covers the analytic case as well as the case of webs. Then the orbit types of the generalized connections are determined for compact structure groups. The stabilizer of a connection is homeomorphic to the holonomy centralizer, i.e. the centralizer of its holonomy group, and the homeomorphism class of the gauge orbit is completely determined by the holonomy centralizer.

It turns out that the ,centralizer, algebra of this action of the unitary group is the so called walled Brauer algebra. This algebra is generated by the following elements: any permutation of the first tensor copies, any permutation of the last copies and contraction maps between pairs of tensor copies, where one of them is from the first half and the other from the second half.
