About the Author

Jiri Blank graduated in 1961 from Czech Technical University and got his PhD from Charles University. Until his premature death in 1990 he was active in mathematical-physics research and teaching. He educated many excellent students. Pavel Exner graduated in 1969 from Charles University. From 1978 to 1990 he worked in Joint Institute for Nuclear Research, Dubna, where he got his PhD and DSc degrees. After the return to Prague he headed a mathematical-physics group in the Nuclear Physics Institute of Academy of Sciences and became a professor of theoretical physics at Charles University. He authored over 150research papers to which more than thousand citations can be found. At present he is a vice president of European Mathematical Society and secretary of IUPAP commission for mathematical physics. Miloslav Havlicek graduated in 1961 from Czech Technical University; he got his PhD from Charles University and DSc at Joint Institute for Nuclear Research, Dubna. He wrote numerous papers on algebraic methods in quantum physics. From 1990 he served repeatedly as dean of the Faculty of Nuclear Sciences and Physical Engineering and head of the Department of Mathematics.


From the reviews of the second edition: Some praise for the previous edition: "I really enjoyed reading this work. It is very well written, by three real experts in the field. It stands quite alone..." (John R. Taylor, Professor of Physics and Presidential Teaching Scholar, University of Colorado at Boulder) "This is an excellent textbook for graduate students and young researchers in mathematics and theoretical physics. ! It is a course from the basics in functional analysis to bounded and unbounded operators, including spectral theory and operator algebras. The exposition is comprehensive, but self-contained." (Michael Demuth, Zentralblatt MATH, Vol. 1163, 2009) "As the title declares, the text presents a comprehensive presentation of linear spaces and their transformations. ! this second edition contains two additional chapters on quantum treatments of waveguides and graphs. ! The book considered is, no doubt, written for physicists and useful for them. ! A valuable feature of this book is the extensive background material and discussions collected into separate sections. ! The book does what it promises and does it well." (Stig Stenholm, Contemporary Physics, January, 2010)
