Spectral Theory of Operators on Hilbert Spaces - Tapa dura

From the reviews: "Kubrusly's book ... situates the spectral theorem in a very interesting broader context. ... Kubrusly intends the book for a one-semester graduate course and ... he closes each of his five (pretty beefy) chapters with sections titled 'Additional Propositions.' ... I think this is a nice idea: it will make for a very solid learning experience indeed. All in all, it's a good book." (Michael Berg, The Mathematical Association of America, August, 2012) "The book under review is intended to offer to graduate students in mathematics, as well as to those studying statistics, engineering, physics and economics, an introductory text for a first course in spectral theory. ... The book is well and clearly written and a large amount of information about the spectrum of linear operators is exhibited within, including several relatively new results. It may be used both as a reference book and also as a textbook ... ." (F.-H. Vasilescu, Mathematical Reviews, January, 2013)
