Functional Analysis
“…an excellent source of facts for anyone working in functional analysis or operator theory.” (Journal of Operator Theory, Vol.53, No.1, 2005)"For years Lax has been counted among the world's very top people in PDEs, so no serious student can afford to ignore his view of the foundations leading up to that subject." (Choice, Vol. 40, No. 4, December 2002)"...attractive...well suited for graduate courses...and useful for research mathematicians." (Mathematical Reviews, 2003a)"...The book is highly recommended to all students of analysis". (Zentralblatt MATH, Vol.1009, No.9, 2003)"A lot of good material, doled out in short chapters." (American Mathematical Monthly, August/September 2003)
