Exempel på hur man kan använda COMMUTATORS i en mening

• The set of all commutators of a group is not in general closed under the group operation, but the subgroup of G generated by all commutators is closed and is called the derived group or the commutator subgroup of G.
• In mathematics, more specifically in abstract algebra, the commutator subgroup or derived subgroup of a group is the subgroup generated by all the commutators of the group.
• As the tensor algebra and the quotient by commutators are left adjoint to these forgetful functors, their composition is left adjoint to the forgetful functor from commutative algebra to vectors or modules, and this proves the desired universal property.
• For example, the commutator of the creation and annihilation operators that are associated with the same boson state equals one, while all other commutators vanish.
• Mark 18 torpedo, ethyl alcohol was no longer required for torpedoes; however, limited quantities of denatured alcohol were (and are) still required by the Electrician's Mates and Interior Communications Electricians on board ship for the purpose of cleaning slip rings, commutators, and carbon brushes on a wide variety of equipment.
• Also, the homopolar generator is unique in that no other rotary electric machine can produce DC without using rectifiers or commutators.
• A slow-running, large series-wound motor with 28 poles and two commutators drove the wheels, without any gear reduction, via an unsprung jackshaft.
• Disabling/destroying IT infrastructure components (uninterruptible power supplies, modems, RTUs, commutators).
• High melting point, used for commutators, armatures, and initial solder joints where remelting when working on nearby joints is undesirable.
