Introduction to Boolean Algebras
Autor Steven Givant, Paul Halmosen Limba Engleză Paperback – 19 noi 2010
Găsim în Introduction to Boolean Algebras o expunere sistematică ce pornește de la capitolul fundamental dedicat inelelor booleene, stabilind rapid puntea necesară între structurile algebrice și logică. Această ediție publicată de Springer reprezintă o rafinare a notelor de curs ale renumitului Paul Halmos, dezvoltate alături de Steven Givant pentru a oferi un text riguros, dar accesibil la nivel de studii aprofundate. Considerăm că forța acestui volum rezidă în echilibrul dintre teoria pură și aplicațiile topologice, incluzând secțiuni esențiale despre funcții continue și spații booleene care lipsesc adesea din tratatele elementare. Lucrarea extinde cadrul propus de Lectures on Boolean Algebras cu date noi și o organizare mai densă, oferind un aparat pedagogic complet prin cele sute de exerciții incluse și manualul de soluții aferent. Structura cărții urmărește o progresie logică impecabilă: de la relații elementare și dualitate, trece prin studiul idealelor și filtrelor, culminând cu Teorema de Reprezentare a lui Stone și dualitatea pentru subalgebre. Spre deosebire de Boolean Algebras de Roman Sikorski, care se concentrează preponderent pe aspectele teoretice ale mulțimilor, volumul de față menține o perspectivă duală, explorând atât natura algebrică, cât și pe cea topologică, fiind astfel o resursă indispensabilă pentru înțelegerea algebrelor de măsură și a algebrelor libere.

GraduateDe ce să citești această carte
Această carte este recomandată studenților de la masterat și doctorat în matematică sau logică. Cititorul câștigă o înțelegere profundă a structurilor booleene printr-o metodă de predare informală, dar precisă, validată de decenii de practică pedagogică. Este un instrument de lucru complet, ideal pentru cercetare individuală datorită soluțiilor incluse și a legăturilor interdisciplinare cu topologia și analiza matematică.
Cuprins
Recenzii
“This is an excellent and much-needed comprehensive undergraduate textbook on Boolean algebras. It contains a complete and thorough introduction to the fundamental theory of Boolean algebras. Aimed at undergraduate mathematics students, the book is, in the first author’s words, “a substantially revised version of Paul Halmos’ “Lectures on Boolean Algebras.” It certainly achieves its stated goal of “steering a middle course between the elementary arithmetic aspects of the subject” and “the deeper mathematical aspects of the theory” of Boolean algebras.”
…
“The book is written for undergraduate students who already have skills in proving theorems. However, since the proofs are so detailed and clear, it could work well as a text for a second or even first course involving substantial proofs. For this reason, it would also make a great book for a student doing independent study. The text is somewhat informal in the sense that sometimes proofs appear in the prose rather than under the heading, “Proof”, but it is always clear when this is being done. Though the book starts with an introduction to Boolean rings, knowledge of group theory or rings is not a prerequisite for using the book.”
…
“In summary, “Introduction to Boolean algebras” is a gem of a text which fills a long-standing gap in the undergraduate literature. It combines the best of both worlds by rigorously covering all the fundamental theorems and topics of Boolean algebra while at the same time being easy to read, detailed, and well-paced for undergraduate students. It is my most highly recommendedtext for undergraduates studying Boolean algebras.”
(Natasha Dobrinen. The Bulletin of Symbolic Logic, Vol. 16 (2), June 2010: 281-282)
"Introduction to Boolean Algebras … is intended for advanced undergraduates. Givant (Mills College) and Halmos … using clear and precise prose, build the abstract theory of Boolean rings and algebras from scratch. … the necessary topological material is developed within the book and an appendix on set theory is included. … Includes an extensive bibliography and more than 800 exercises at all levels of difficulty. Summing Up: Highly recommended. Upper-division undergraduates, graduate students, researchers, and faculty." (S. J. Colley, Choice, Vol. 46 (10), June 2009)
“The authors have written a book for advanced undergraduates and beginning graduate students. … The authors start with the definition of Boolean rings and Boolean algebras, give examples and basic facts and compare both notions. … There are a large number of exercises of varying level of difficulty. Hints for the solutions of the harder problems are given in an appendix. A detailed solutions manual for all exercises is available for instructors. The book can serve as a basis for a variety of courses.” (Martin Weese, Zentralblatt MATH, Vol. 1168, 2009)
Textul de pe ultima copertă
Highlights of the book include the normal form theorem; the homomorphism extension theorem; the isomorphism theorem for countable atomless Boolean algebras; the maximal ideal theorem; the celebrated Stone representation theorem; the existence and uniqueness theorems for canonical extensions and completions; Tarski’s isomorphism of factors theorem for countably complete Boolean algebras, and Hanf’s related counterexamples; and an extensive treatment of the algebraic-topological duality, including the duality between ideals and open sets, homomorphisms and continuous functions, subalgebras and quotient spaces, and direct products and Stone-Cech compactifications.
A special feature of the book is the large number of exercises of varying levels of difficulty, from routine problems that help readers understand the basic definitions and theorems, to intermediate problems that extend or enrich material developed in the text, to harder problems that explore important ideas either not treated in the text, or that go substantially beyond its treatment. Hints for the solutions to the harder problems are given in an appendix. A detailed solutions manual for all exercises isavailable for instructors who adopt the text for a course.

Descriere
This book is an informal though systematic series of lectures on Boolean algebras. It contains background chapters on topology and continuous functions and includes hundreds of exercises as well as a solutions manual.
