From the reviews:

“The aim of Intermediate Spectral Theory and Quantum Dynamics is to provide advanced undergraduate and graduate students with this understanding of the mathematical intricacies of non-relativistic quantum mechanics of a single particle. … a concise introduction to the spectral theory of unbounded operators … . ends with a comprehensive bibliography which contains references to the original literature and further reading and an extensive index of the material presented. … I have found this book an interesting read which I will consult in future … .” (Jörg Bernhard Götte, Contemporary Physics, Vol. 52 (3), May-June, 2011)

“The book gives an introduction to spectral theory on the graduate or advanced undergraduate level. … The variety of topics is remarkably large for a book at the textbook level, and also some recent results are included. … In conclusion, Intermediate spectral theory and quantum dynamics is a mostly complete and very readable introduction to this classical area of mathematics. Students will surely appreciate the many examples and exercises.” (Rupert L. Frank, Mathematical Reviews, Issue 2011 m)
