The basic theory of linear (bounded and unbounded) operators in Hilbert spaces and special classes of linear operators - compact, Hilbert-Schmidt, trace class, and Schrödinger operators, as needed in quantum physics and quantum information theory – are explored.
"This book gives a detailed survey on mathematical methods in physics ... . The book is very suitable for students of physics, mathematics or engineering with a good background in analysis and linear algebra. ... All in all, the book has a high didactical and scientific quality so that it can be recommended for both graduate students and researchers." (Michael Demuth, zbMATH 1330.46001, 2016)
