Naive Set Theory (Dover Books on Mathematics). The theory as he presents it deals with arbitrary spectral measures, including the multiplicity theory of normal operators on a not necessarily separable Hilbert space. Category Theory in Context (Aurora: Dover Modern Math Originals). His explication covers, as another useful special case, the multiplicity theory of unitary representations of locally compact abelian groups. Suitable for advanced undergraduates and graduate students in mathematics, this volume's sole prerequisite is a background in measure theory.

North-Holland Series in Applied Mathematics and Mechanics, Volume 6: Introduction to Spectral Theory in Hilbert Space focuses on the mechanics, principles, and approaches involved in spectral theory in Hilbert space. The publication first elaborates on the concept and specific geometry of Hilbert space and bounded linear operators. Discussions focus on projection and adjoint operators, bilinear forms, bounded linear mappings, isomorphisms, orthogonal subspaces, base, subspaces, finite dimensional Euclidean space, and normed linear spaces.

He taught at the University of Chicago and the University of Michigan as well as other universities and made significant contributions to several areas of mathematics, including mathematical logic, probability theory, ergodic theory, and functional analysis. Series: Dover Books on Mathematics.

This text introduces students to Hilbert space and bounded self-adjoint operators, as well as the spectrum of an operator and its spectral decomposition. The author, Emeritus Professor of Mathematics at the University of Innsbruck, Austria, has ensured that the treatment is accessible to readers with no further background than a familiarity with analysis and analytic geometry.Starting with a definition of Hilbert space and its geometry, the text explores the general theory of bounded linear operators, the spectral analysis of compact linear operators, and unbounded self-adjoint operators. Extensive appendixes offer supplemental information on the graph of a linear operator and the Riemann-Stieltjes and Lebesgue integration.

Helmberg's book provides a superb introduction to Hilbert Spaces and Spectral theory. It's an exceptionally clear, careful, yet concise exposition for anyone who is, as the author states: "interested in the topic but lacks the time or desire to fill in gaps ... or to work through an inspiring set of exercises considered to form an integral part of the text (p. viii)". (I personally dislike books that make exercises integral to the exposition as this makes self-study more difficult than necessary.)

I rank this book as beginning graduate level or for math majors, advanced undergraduate. Prerequisites are minimal for the topic but include standard calculus, linear algebra at the level of Axler's Linear Algebra Done Right, basic analysis, basic topology (metric space, inner product space, normed space) and a little group theory. Other books I like include Rynne & Youngson Linear Functional Analysis (Springer Undergraduate Mathematics Series) and the Wiley classic Kreyszig Introductory Functional Analysis with Applications. Helmberg is a bit more advanced than Rynne / Youngson or Kreyszig. Both Kreyszig and Rynee / Youngson provide more mathematical background than Helmberg. Note that Kreyzsig devotes chapter 11 to use of unbounded linear operators in quantum mechanics. Also, if you're more interested in quantum mechanics applications, I'd check out Jordan's Linear Operators for Quantum Mechanics (Dover Books on Mathematics). Jordon, however, is a very concise, graduate level text and expects a great deal of mathematical maturity.

Even though the exposition is kind to the reader, the pace is nice: Hilbert spaces on p. 23; spectrum of a linear operator p.157. Ex appendices and back matter, book is only 309 pp. but covers: Ch.1: Concept of a Hilbert Space [1-35]; Ch. 2: Specific geometry of Hilbert space [36-70]; Ch. 3: Bounded linear operators [71-116]; Ch. 4: General theory of linear operators [117-176]; Ch. 5: Spectral analysis of compact linear operators [177-218]; Ch. 6: Spectral analysis of bounded linear operators [219-287]; Ch. 7: Spectral analysis of unbounded selfadjoint linear operators [288-309].

Anyone seriously interested in the mathematical details of the Hilbert Space formalism of Quantum Mechanics could profit from reading Helmberg. The book is very nicely produced, with large enough font for aging eyes. And since it's Dover, the price is right. Note that the original publication date was 1969 but hey, the math has not changed.

So before you buy some expensive book on this topic, you owe it to yourself to check out Helmberg: you can get it and still afford those lattes you need to read it!

Nice expository book.

This book is, in my opinion, certainly the best written mathematical textbook I ever come across. It's highly readable and very well presented. Let alone there is hardly any error unlike more modern books. Strongly recommend this book to whoever starting on the subject.
