Operators and Operator Algebras

1973
Almost all the material discussed in this chapter will be needed later but a reader who is somewhat familiar with it already might prefer to use it only for reference during the detailed study of some of the later chapters. The topics of this chapter are both important and interesting. The following elementary and concise summary of this part of linear

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 ...
