Berberian S. Lectures in functional analysis and operator theory

Springer, 1974 — 358 p.
The book is based on lecture notes for a one-year course, addressed to general mathematics students at the second year graduate level, which I have offered on three occasions. {Twice at the University of Iowa (1961-62, 1965-66), once at the University of Texas (1969-70)}. I helped myself to generous portions of expositions I have admired. These include a course of lectures by Paul R. Halmos, entitled "Topological algebra"(University of Chicago, 1952); a mimeographed set of lecture notes, with the same title, by Irving Kaplansky (University of Chicago, 1952); Arthur H. Kruse's personal notes on Kaplansky's course; and Chapters I and II of N. Bourbaki's Espaces vectoriels topologiques.
