Abstract
Here, we introduce the basic theory of the Cuntz semigroup. Any proofs not contained in these notes can be found in Ara–Brown–Guido–Lledo–Perera–Toms [1], but no originality is claimed there. Most of the results here are due to Cuntz [9], Kirchberg–Rørdam [17], and Rørdam [26]. We assume that all C*-algebras are separable unless otherwise noted.
