This book is intended for the student or researcher who could benefit from functional analytic methods, but who does not have an extensive background and does not plan to make a career as an analyst. It develops topology, convexity, Banach lattices, integration, correspondences (multifunctions), and the analytic approach to Markov processes. Many of the results were previously available only in esoteric monographs. The choice of material was motivated from problems in control theory and economics, although the material is more applicable than applied.
This book is a totally cool introduction to functional analysis. The presentation is clear and easy to follow without being slow paced, and in particular I like the treatment of weak* convergence more than Billingsley's.
Before reading this book, I knew squat. Afterward, of course I still know very little, but it taught me enough to be able to make respectable progress on some problems in infinite dimensional vector spaces. So I am a content reader.
