Thoroughly revised, updated, expanded, and reorganized to serve as
a primary text for mathematics courses, Introduction to Set Theory,
Third Edition covers the basics: relations, functions, orderings,
finite, countable, and uncountable sets, and cardinal and ordinal
numbers. It also provides five additional self-contained chapters,
consolidates the material on real numbers into a single updated
chapter affording flexibility in course design, supplies
end-of-section problems, with hints, of varying degrees of
difficulty, includes new material on normal forms and Goodstein
sequences, and adds important recent ideas including filters,
ultrafilters, closed unbounded and stationary sets, and partitions.
This text introduces topos theory, a development in category theory
that unites important but seemingly diverse notions from algebraic
geometry, set theory, and intuitionistic logic. Topics include
local set theories, fundamental properties of toposes, sheaves,
local-valued sets, and natural and real numbers in local set
theories. 1988 edition.
Set theory is a branch of mathematics with a special subject
matter, the infinite, but also a general framework for all modern
mathematics, whose notions figure in every branch, pure and
applied. This Element will offer a concise introduction, treating
the origins of the subject, the basic notion of set, the axioms of
set theory and immediate consequences, the set-theoretic
reconstruction of mathematics, and the theory of the infinite,
touching also on selected topics from higher set theory,
controversial axioms and undecided questions, and philosophical
issues raised by technical developments.
This exploration of a notorious mathematical problem is the work of
the man who discovered the solution. The independence of the
continuum hypothesis is the focus of this study by Paul J. Cohen.
It presents not only an accessible technical explanation of the
author's landmark proof but also a fine introduction to
mathematical logic. An emeritus professor of mathematics at
Stanford University, Dr. Cohen won two of the most prestigious
awards in mathematics: in 1964, he was awarded the American
Mathematical Society's Bocher Prize for analysis; and in 1966, he
received the Fields Medal for Logic.
In this volume, the distinguished mathematician offers an
exposition of set theory and the continuum hypothesis that employs
intuitive explanations as well as detailed proofs. The
self-contained treatment includes background material in logic and
axiomatic set theory as well as an account of Kurt Godel's proof of
the consistency of the continuum hypothesis. An invaluable
reference book for mathematicians and mathematical theorists, this
text is suitable for graduate and postgraduate students and is rich
with hints and ideas that will lead readers to further work in
mathematical logic.
This book introduces a new research direction in set theory: the
study of models of set theory with respect to their extensional
overlap or disagreement. In Part I, the method is applied to
isolate new distinctions between Borel equivalence relations. Part
II contains applications to independence results in
Zermelo-Fraenkel set theory without Axiom of Choice. The method
makes it possible to classify in great detail various paradoxical
objects obtained using the Axiom of Choice; the classifying
criterion is a ZF-provable implication between the existence of
such objects. The book considers a broad spectrum of objects from
analysis, algebra, and combinatorics: ultrafilters, Hamel bases,
transcendence bases, colorings of Borel graphs, discontinuous
homomorphisms between Polish groups, and many more. The topic is
nearly inexhaustible in its variety, and many directions invite
further investigation.
This book provides an introduction to axiomatic set theory and
descriptive set theory. It is written for the upper level
undergraduate or beginning graduate students to help them prepare
for advanced study in set theory and mathematical logic as well as
other areas of mathematics, such as analysis, topology, and
algebra.The book is designed as a flexible and accessible text for
a one-semester introductory course in set theory, where the
existing alternatives may be more demanding or specialized. Readers
will learn the universally accepted basis of the field, with
several popular topics added as an option. Pointers to more
advanced study are scattered throughout the text.
Suitable for upper-level undergraduates, this accessible approach
to set theory poses rigorous but simple arguments. Each definition
is accompanied by commentary that motivates and explains new
concepts. Starting with a repetition of the familiar arguments of
elementary set theory, the level of abstract thinking gradually
rises for a progressive increase in complexity.
A historical introduction presents a brief account of the growth of
set theory, with special emphasis on problems that led to the
development of the various systems of axiomatic set theory.
Subsequent chapters explore classes and sets, functions, relations,
partially ordered classes, and the axiom of choice. Other subjects
include natural and cardinal numbers, finite and infinite sets, the
arithmetic of ordinal numbers, transfinite recursion, and selected
topics in the theory of ordinals and cardinals. This updated
edition features new material by author Charles C. Pinter.
In this book, Claire Voisin provides an introduction to
algebraic cycles on complex algebraic varieties, to the major
conjectures relating them to cohomology, and even more precisely to
Hodge structures on cohomology. The volume is intended for both
students and researchers, and not only presents a survey of the
geometric methods developed in the last thirty years to understand
the famous Bloch-Beilinson conjectures, but also examines recent
work by Voisin. The book focuses on two central objects: the
diagonal of a variety--and the partial Bloch-Srinivas type
decompositions it may have depending on the size of Chow groups--as
well as its small diagonal, which is the right object to consider
in order to understand the ring structure on Chow groups and
cohomology. An exploration of a sampling of recent works by Voisin
looks at the relation, conjectured in general by Bloch and
Beilinson, between the coniveau of general complete intersections
and their Chow groups and a very particular property satisfied by
the Chow ring of K3 surfaces and conjecturally by hyper-Kahler
manifolds. In particular, the book delves into arguments
originating in Nori's work that have been further developed by
others."
Lucidly and gradually explains sets and relations, the natural number sequence and its generalization, extension of natural numbers to real numbers, logic, informal axiomatic mathematics, Boolean algebras, informal axiomatic set theory, several algebraic theories, and first-order theories. Its clarity makes this book excellent for self-study.
If you want top grades and thorough understanding of set theory and related topics, this powerful study tool is the best tutor you can have! It takes you step-by-step through the subject and gives you 530 accompanying related problems with fully worked solutions. You also get plenty of practice problems to do on your own, working at your own speed. (Answers at the back show you how youre doing.) This new edition features improved problems in the ordinals, cardinals, and transfinite series chapters, plus new coverage of real numbers and integers.
Set Theory has experienced a rapid development in recent years, with major advances in forcing, inner models, large cardinals and descriptive set theory. The present book covers each of these areas, giving the reader an understanding of the ideas involved. It can be used for introductory students and is broad and deep enough to bring the reader near the boundaries of current research. Students and researchers in the field will find the book invaluable both as a study material and as a desktop reference.
One of the greatest revolutions in mathematics occurred when
Georg Cantor (1845-1918) promulgated his theory of transfinite
sets. This revolution is the subject of Joseph Dauben's important
studythe most thorough yet writtenof the philosopher and
mathematician who was once called a "corrupter of youth" for an
innovation that is now a vital component of elementary school
curricula.
Set theory has been widely adopted in mathematics and
philosophy, but the controversy surrounding it at the turn of the
century remains of great interest. Cantor's own faith in his theory
was partly theological. His religious beliefs led him to expect
paradoxes in any concept of the infinite, and he always retained
his belief in the utter veracity of transfinite set theory. Later
in his life, he was troubled by recurring attacks of severe
depression. Dauben shows that these played an integral part in his
understanding and defense of set theory.
This Element is an exposition of second- and higher-order logic and
type theory. It begins with a presentation of the syntax and
semantics of classical second-order logic, pointing up the
contrasts with first-order logic. This leads to a discussion of
higher-order logic based on the concept of a type. The second
Section contains an account of the origins and nature of type
theory, and its relationship to set theory. Section 3 introduces
Local Set Theory (also known as higher-order intuitionistic logic),
an important form of type theory based on intuitionistic logic. In
Section 4 number of contemporary forms of type theory are
described, all of which are based on the so-called 'doctrine of
propositions as types'. We conclude with an Appendix in which the
semantics for Local Set Theory - based on category theory - is
outlined.

In recent years, substantial efforts are being made in the
development of reliability theory including fuzzy reliability
theories and their applications to various real-life problems.
Fuzzy set theory is widely used in decision making and multi
criteria such as management and engineering, as well as other
important domains in order to evaluate the uncertainty of real-life
systems. Fuzzy reliability has proven to have effective tools and
techniques based on real set theory for proposed models within
various engineering fields, and current research focuses on these
applications. Advancements in Fuzzy Reliability Theory introduces
the concept of reliability fuzzy set theory including various
methods, techniques, and algorithms. The chapters present the
latest findings and research in fuzzy reliability theory
applications in engineering areas. While examining the
implementation of fuzzy reliability theory among various industries
such as mining, construction, automobile, engineering, and more,
this book is ideal for engineers, practitioners, researchers,
academicians, and students interested in fuzzy reliability theory
applications in engineering areas.
