Operators and Operator Theory

[von_Bismarck]

Presently I am very much interested in learning of operators and operator theory. Any information provided would be greatly appreciated, esp. in the form of recommended books or websites (the more rigorous, the better).

Thank you in advance!

How much linear algebra do you know? Apostol's Calcus Vol II covers an intro to that very rigorously...

In my opinion, Shankar's Principles of Quantum Mechanics gives the best introduction to formalism.

IMO a good introduction for physicist is a set by Reed and Simon, a standard reference for anyone who want to understand math behind quantum theory.
