Integration I: Chapters 1-6

by N. Bourbaki

This is the sixth and last of the books that form the core of the Bourbaki series, comprising chapters 1-6 in English translation. One striking feature is its exposition of abstract harmonic analysis and the structure of locally compact Abelian groups. This English edition corrects misprints, updates references, and revises the definition of the concept of measurable equivalence relations.

Integration II: Chapters 7–9

by N. Bourbaki

Integration is the sixth and last of the books that form the core of the Bourbaki series; it draws abundantly on the preceding five Books, especially General Topology and Topological Vector Spaces, making it a culmination of the core six. The power of the tool thus fashioned is strikingly displayed in Chapter II of the author's Théories Spectrales, an exposition, in a mere 38 pages, of abstract harmonic analysis and the structure of locally compact abelian groups. The first volume of the English translation comprises Chapters 1-6; the present volume completes the translation with the remaining Chapters 7-9. Chapters 1-5 received very substantial revisions in a second edition, including changes to some fundamental definitions. Chapters 6-8 are based on the first editions of Chapters 1-5. The English edition has given the author the opportunity to correct misprints, update references, clarify the concordance of Chapter 6 with the second editions of Chapters 1-5, and revise the definition of a key concept in Chapter 6 (measurable equivalence relations).

Théories spectrales: Chapitres 1 et 2

by N. Bourbaki

Les Éléments de mathématique de Nicolas BOURBAKI ont pour objet une présentation rigoureuse, systématique et sans prérequis des mathématiques depuis leurs fondements.Le Livre de Théories spectrales est consacré à l'étude des algèbres normées et de leurs applications. Le premier chapitre met en place la théorie fondamentale des algèbres de Banach et des algèbres stellaires. Nous y présentons l'équivalence de catégories entre algèbres stellaires commutatives et espaces topologiques localement compacts, ainsi que le calcul fonctionnel holomorphe en plusieurs variables dans une algèbre de Banach commutative. La transformation de Fourier, qui est l'un des outils mathématiques les plus universels, est étudiée au second chapitre, dans le cadre des groupes localement compacts commutatifs. Le texte est complété par de nombreux exercices. Ces deux chapitres forment une édition entièrement refondue de l'édition de 1967. The Elements of Mathematics of Nicolas Bourbaki have the goal of giving a rigorous and systematic presentation of mathematics starting from the foundations, without prerequisites. The book of Spectral Theories is devoted to the study of normed algebras and their applications. The first chapter establishes the basic theory of Banach algebras and C*-algebras. We present the equivalence of categories between commutative C*-algebras and locally compact topological spaces, as well as the holomorphic functional calculus in several variables in a commutative Banach algebra.The Fourier transform, which is one of the most universal mathematical tools, is studied in the second chapter, in the context of locally compact commutative topological groups.The text is accompanied by many exercices.These two chapters are completely updated new versions of the 1967 original edition.

Complex Analysis (Hindustan Publishing Corporation)

by Andrei Bourchtein Ludmila Bourchtein

This book discusses all the major topics of complex analysis, beginning with the properties of complex numbers and ending with the proofs of the fundamental principles of conformal mappings. Topics covered in the book include the study of holomorphic and analytic functions, classification of singular points and the Laurent series expansion, theory of residues and their application to evaluation of integrals, systematic study of elementary functions, analysis of conformal mappings and their applications—making this book self-sufficient and the reader independent of any other texts on complex variables. The book is aimed at the advanced undergraduate students of mathematics and engineering, as well as those interested in studying complex analysis with a good working knowledge of advanced calculus. The mathematical level of the exposition corresponds to advanced undergraduate courses of mathematical analysis and first graduate introduction to the discipline. The book contains a large number of problems and exercises, making it suitable for both classroom use and self-study. Many standard exercises are included in each section to develop basic skills and test the understanding of concepts. Other problems are more theoretically oriented and illustrate intricate points of the theory. Many additional problems are proposed as homework tasks whose level ranges from straightforward, but not overly simple, exercises to problems of considerable difficulty but of comparable interest.

Elementary Functions

by Andrei Bourchtein Ludmila Bourchtein

This textbook focuses on the study of different kinds of elementary functions ubiquitous both in high school Algebra and Calculus. To analyze the functions ranging from polynomial to trigonometric ones, it uses rudimentary techniques available to high school students, and at the same time follows the mathematical rigor appropriate for university level courses.Contrary to other books of Pre-Calculus, this textbook emphasizes the study of elementary functions with rigor appropriate for university level courses in mathematics, although the exposition is confined to the pre-limit topics and techniques. This makes the book useful, on the one hand, as an introduction to mathematical reasoning and methods of proofs in mathematical analysis, and on the other hand, as a preparatory course on the properties of different kinds of elementary functions.The textbook is aimed at university freshmen and high-school students interested in learning strict mathematical reasoning and in preparing a solid base for subsequent study of elementary functions at advanced level of Calculus and Analysis. The required prerequisites correspond to the level of the high school Algebra. All the preliminary concepts and results related to the elementary functions are covered in the initial part of the text. This makes the textbook suitable for both classroom use and self-study.
