I am taking a course on operator algebra this semester. My instructor has suggested a reference “Kadinson and Ringrose.” Are there any other good/standard references for this subject that I can look up?
The book by Kadison and Ringrose does not contain a number modern topics (irrational rotation algebras, Cuntz algebras, K-theory etc.). I have used the following books for my lectures:
G.Murphy “$C^*$-algebras and operator theory”
K.Davidson “$C^*$-algebras by example.”
A nice introduction to K-theory of $C^*$-algebras with prerequisites on $C^*$-algebras is
N.E.Wegge-Olsen “K-theory and $C^*$-algebras. A friendly approach.”
On the other hand I find the book by Kadison and Ringrose much easier to read.
The classical monograph by Dixmier can be used as encyclopedia of basic $C^*$-algebra theory.
