Analysis in Vector Spaces
The concepts and theorems of advanced calculus combined with related computational methods are essential to understanding nearly all areas of quantitative science. Analysis in Vector Spaces presents the central results of this classic subject through rigorous arguments, discussions, and examples. The book aims to cultivate not only knowledge of the major theoretical results, but also the geometric intuition needed for both mathematical problem-solving and modeling in the formal sciences.
The authors begin with an outline of key concepts, terminology, and notation and also provide a basic introduction to set theory, the properties of real numbers, and a review of linear algebra. An elegant approach to eigenvector problems and the spectral theorem sets the stage for later results on volume and integration. Subsequent chapters present the major results of differential and integral calculus of several variables as well as the theory of manifolds. Additional topical coverage includes:
Sets and functions
Normed vector spaces
First- and higher-order derivatives
Diffeomorphisms and manifolds
Integration on manifolds
Basic point set topology
Numerous examples and exercises are provided in each chapter to reinforce new concepts and to illustrate how results can be applied to additional problems. Furthermore, proofs and examples are presented in a clear style that emphasizes the underlying intuitive ideas. Counterexamples are provided throughout the book to warn against possible mistakes, and extensive appendices outline the construction of real numbers, include a fundamental result about dimension, and present general results about determinants.
Assuming only a fundamental understanding of linear algebra and single variable calculus, Analysis in Vector Spaces is an excellent book for a second course in analysis for mathematics, physics, computer science, and engineering majors at the undergraduate and graduate levels. It also serves as a valuable reference for further study in any discipline that requires a firm understanding of mathematical techniques and concepts.

All proofs have been written with the student reader in mind. In each proof, the notation and methods have been chosen to maximize clarity and transparency.
A large number of examples are included to reinforce new concepts and to illustrate how a result or technique can be applied to additional problems. Counter-examples are also given throughout the book to warn the students against possible mistakes in the subject.
The book is self-contained, and the background material in the first few chapters is sufficient to enable well-motivated students to read the book without undue difficulties.
To avoid possible ambiguities and misunderstandings, terminology and notation are carefully defined before being used.
An extensive collection of exercises is provided, and full solutions are included in an accompanying Student Solutions Manual.
