Set theory Set theory is a branch of mathematical logic that studies sets, which informally are collections of objects.Although any type of object can be collected into a set, set theory is applied most often to objects that are relevant to mathematics. Set Theory Stanford Encyclopedia of Philosophy Set theory is the mathematical theory of well determined collections, called sets, of objects that are called members, or elements, of the set.Pure set theory deals exclusively with sets, so the only sets under consideration are those whose members are also sets. Naive set theory Nave set theory is any of several theories of sets used in the discussion of the foundations of mathematics Unlike axiomatic set theories, which are defined using formal logic, nave set theory is defined informally, in natural language.It describes the aspects of mathematical sets familiar in discrete mathematics for example Venn diagrams and symbolic reasoning about their Boolean set theory Basics, Examples, Formulas Britannica Set theory, branch of mathematics that deals with the properties of well defined collections of objects, which may or may not be of a mathematical nature, such as numbers or functions.The theory is less valuable in direct application to ordinary experience than as a basis for precise and adaptable terminology for the definition of complex and sophisticated mathematical concepts.

Set theory MacTutor History of Mathematics The history of set theory is rather different from the history of most other areas of mathematics For most areas a long process can usually be traced in which ideas evolve until an ultimate flash of inspiration, often by a number of mathematicians almost simultaneously, produces a discovery of major importance. Set theory The Neumann Bernays Gdel axioms Britannica Only a sketchy account of set theory is given here Set theory is a logic of classes i.e of collections finite or infinite or aggregations of objects of any kind, which are known as the members of the classes in question Some logicians use Sets An Introduction A set is a collection of objects that have something in common or follow a rule.The objects in the set are called its elements Set notation uses curly braces, with elements separated by commas So the set of outwear for Kyesha would be listed as follows Mathematics Introduction of Set theory GeeksforGeeks A Set is a unordered collection of objects, known as elements or members of the set An element a belong to a set A can be written as a A , a A denotes that a is not an element of the set A Representation of a Set AN INTRODUCTION TO SET THEORY mathronto Chapter Introduction Set Theory is the true study of in nity This alone assures the subject of a place prominent in human culture But even , Set Theory is the milieu

Now this is how to really understand forcing. No offense to Badiou, obviously, for not making this foundational book dispensable. Even (& especially) careful readers of Being and Event should rather follow his example and work through this. Confirms Cohen's vaunted pedagogical elucidatory talents with compound interest. Vastly easier than Cohen's original journal papers on forcing, you'll be able to follow this if you're as sharp as a Harvard undergrad (and who isn't?)
well i'm going to read this book again in the near future to get a more complete grasp on all the topics. i read it too slowly! school got in the way. still, though its only 150 pages this book contains an astounding amount of, uh, good theorems and shit. would like if it was typeset using LaTeX, but hey i'm just happy dover is publishing it again. (and for so cheap!). a few typos. a few of the proofs could have maybe used a bit more detail. all in all though, really well organized, compact, and [...]
20090213. Thanks, Dover, for reprinting this classic (a perennial favorite on outofprintmath)!
Following a presumptuous page and a half introduction, Cohen presents the standard symbols of first order logic  "and" "or" "not" "ifen" "if and only if"  and then the two second order quantifiers  "some" "all"  bringing the reader to confront Godel's completeness theorem ( roughly, the cardinality of a model does not exceed the cardinality of the statement set it interprets ) on page 11.I'm saved by having studied logic and the completeness theorems before. and by Cohen's adept skill at exp [...]
