Commutativity and Homotopy-Commutativity [PDF]

, 1964
The aim of this section is to show, by means of the methods developed in Chapter 3, that for an associative H-space G there exist maps G× G → G satisfying certain commutativity conditions (Theorem 4.5). As will be explained in Remarks 4.6 this result is related to the work of other authors on homotopy-commutativity.

Equilibrium commuting [PDF]

Economic Theory, 2017
We consider the role of a nonlinear commuting cost function in determination of the equilibrium commuting pattern where all agents are mobile. Previous literature has considered only linear commuting cost, where in equilibrium, all workers are indifferent about their workplace location.

Commutators of operators

American Journal of Mathematics, 1952
A mathematical formulation of the famous Heisenberg uncertainty principle is that a certain pair of linear transformations P and Q satisfies, after suitable normalizations, the equation PQ - QP = 1. It is easy enough to produce a concrete example of this behavior; consider L2(-∞, +∞) and let P and Q be the differentiation transformation and the ...

To Commute or Not Commute, the Homesteader’s Dilemma [PDF]

Great Plains Quarterly, 2018
After a long hiatus, scholars are reassessing the Homestead Act of 1862. Most scholars see the Act as a failure, partly because they believe its operation involved massive fraud, for which they blame its “commutation” clause as a chief reason. This article provides a fresh look at homesteading commutations, reframing the question to consider under what

Commutator design for commutator fusing

1973 EIC 11th Electrical Insulation Conference, 1973
One of the biggest problems encountered in the production of universal or D.C. electric motors has been the method and practice of joining the armature's coil wires to the commutator. For years most manufactuers either soft soldered or brazed the coil wires to the commutator.
