Sorry, no etymologies found.


  • Application is not assumed to possess additional properties (such as commutativity), because its intended interpretation is function application.

    Combinatory Logic

  • You have to give up commutativity to get the quaternions.

  • Now you must give up both commutativity and associativity, but you still have a “division algebra.”

    The Volokh Conspiracy » Yow!

  • It could well be that there is a way of getting to the quasi-local, infinity-free expansion by solving the spacelike commutativity/anticommutativity requirement directly, but if there is, I have not found it yet.

    String Theory is Losing the Public Debate

  • For example the commutativity law x+y = y+x holds for all real values of x and y.


  • It follows that the non-commutativity of observables imposes limits on the possibilities of joint existence of properties.

  • For instance, to express the commutativity of addition the user would enter the Lisp expression
