The concept was first introduced by Georg Cantor in 1872 and he developed set theory in large part to study derived sets on the real line.
In 1908, Ernst Zermelo proposed the first axiomatic set theory, Zermelo set theory.
In modern set theory, we usually use the Von Neumann cardinal assignment, which uses the theory of ordinal numbers and the full power of the axioms of choice and replacement.
Set theory, was founded by a single paper in 1874 by Georg Cantor:"On a Property of the Collection of All Real Algebraic Numbers".
For a further development of mathematics in NFU, with a comparison to the development of the same in ZFC, see implementation of mathematics in set theory.
The axiom of choice without replacement(ZC set theory) is not strong enough to show that Borel sets are determined; for this, replacement is required.
Systems of constructive set theory, such as CST, CZF, and IZF, embed their set axioms in intuitionistic logic instead of first order logic.
Because RA can express Peano arithmetic and set theory, Gödel's incompleteness theorems apply to it; RA is incomplete, incompletable, and undecidable.
If κ is an inaccessible cardinal, then Vκ is a model of Zermelo-Fraenkel set theory(ZFC) itself, and Vκ+1 is a model of Morse- Kelley set theory.
Each chapter surveys some aspect of contemporary research in set theory.
Barkley Rosser proved that Quine's set theory was subject to the Burali-Forti paradox.
The momentum of set theory was such that debate on the paradoxes did not lead to its abandonment.
De Morgan proposes two laws of set theory that are now known as"de Morgan's laws".
Therefore, no useful axiomatization of set theory can use unrestricted comprehension, at least not with classical logic.
Russell discovers"Russell's paradox" which illustrates in a simple fashion the problems inherent in naive set theory.
Therefore, no useful axiomatisation of set theory can use unrestricted comprehension, at least not with classical logic.
(Since we are not trying to do set theory here, we just treat V as a unary predicate.).
This utility of set theory led to the article"Mengenlehre" contributed in 1898 by Arthur Schoenflies to Klein's encyclopedia.
This past July, Malliaris and Shelah were awarded the Hausdorff medal, one of the top prizes in set theory.
Specifically, Alternative Set Theory(or AST) may refer to a particular set theory developed in the 1970s and 1980s by Petr Vopěnka and his students.
