This book is an introductory text in functional analysis. Unlike many modern treatments, it begins with the particular and works its way to the more general.
From the reviews: "This book is an excellent text for a first graduate course in functional analysis....Many interesting and important applications are included....It includes an abundance of exercises, and is written in the engaging and lucid style which we have come to expect from the author." MATHEMATICAL REVIEWS
Additional exercises, updated references and a rewritten final chapter (Fredholm Theory) distinguish this new edition of a text in which the renowned John Conway undertakes to acquaint graduate students with the most important of the many faces of "functional analysis". He writes with engaging informality (verbal, not mathematical), and has the rare good sense to proceed from the concrete to the abstract, rather than the reverse. (NW) Annotation c.
