Functional analysis by walter rudins In addition to Functional Analysis, Second Edition, Walter Rudin is the author of two other Principles of Mathematical Analysis and Real and Complex Analysis, whose widespread use is illustrated by the fact that they have been translated into a total of 13 languages. He wrote Principles of Mathematical Analysis while he was a C.L.E. Moore Instructor at the Massachusetts Institute of Technology-just two years after receiving his Ph.D. at Duke University. Later, he taught at the University of Rochester, and is now a Vilas Research Professor at the University of Wisconsin- Madison. In the past, he has spent leaves at Yale University, the University of California in La Jolla, and the University of Hawaii. Dr. Rudin's research has dealt mainly with harmonic analysis and with complex variables. He has written three research monographs on these Fourier Analysis on Groups, Function Theory in Polydiscs, and Function Theory in the Unit Ball of Cn
