I wish to do a reading course in Operator Theory. Thus, I am looking for some references in the area. Right now, I have the following two sources available:

  1. Unbounded Self-Adjoint Operators on Hilbert Spaces - Konrad Schumdgen.
  2. A course in Operator Theory - J.B. Conway.
  3. Linear Operators on Hilbert Spaces - J. Wiedmann.

Could someone please provide me more references?

Moreover, are there some standard topics that I would do well to cover?


Two popular books are :

  1. Douglas' "Banach algebra techniques in Operator Theory" and
  2. Murphy's "C* Algebras and Operator theory"

I like Douglas' style, but content-wise, I think Murphy is more standard.

Operator theory and Operator Algebras have a large overlap (particularly at the early-graduate-school level), so any book that professes to teach Operator Algebras would work just as well.

  • $\begingroup$ $+1$ for Murphy's Book.. :) $\endgroup$ – user87543 Sep 14 '13 at 17:32

I strongly feel




these would help you.

These are actually lecture notes form a M.Sc course in University of Hyderabad (taught by Dr.T.K.S.Moothathu). He has covered some advanced topics also.. I took his course but dont ask me anything... :P

all the best..
