Math 371: 8.4 for April 8th

(1) Is the ,centralizer, of a (a being an ,element, of the group G) similar to the center of a group, Z(G)? I'm not quite sure I understand how the meaning of conjugate is being used in this section. The proofs of the Sylow theorems are hard to follow, not sure where they are coming up with some stuff.

Wave function collapse - Wikipedia

In quantum mechanics, ,wave function collapse, occurs when a wave function—initially in a superposition of several eigenstates—reduces to a single eigenstate due to interaction with the external world. This interaction is called an "observation".It is the essence of a measurement in quantum mechanics which connects the wave function with classical observables like position and momentum.

Abstract Algebra and Discrete Mathematics Division Rings

When an ,atom,, i.e. a conjugate of w, is conjugated, the result is another conjugate of w, which is in F, so we're off to a good start. ... , and let w be an ,element, in D. The ,centralizer, of w is the set of elements that commute with w. Verify that this is a division subring of D. We will prove this ,centralizer, is infinite.
