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. This is similar to Euclid’s axioms of geometry, and, in some sense, the group axioms. Set Theory 2. Intuitively, a set is a collection of all elements that satisfy a certain given property.

This is known as axiomatic set theory. His contributions to set theory as well as to the study of natural numbers and modular lattices are equally important. This page sets out the principles of sets, and the elements within them. Then . In particular, he proved that there are dif-ferent inﬁnite cardinalities: the quantity of natural numbers is strictly smaller than the quantity of real numbers. ha;bi= ffag;fa;bgg Theorem 1.5. ha;bi= hc;dii a= cand b= d. Proof. The second axiomatization of set theory (see the table of Neumann-Bernays-Gödel axioms) originated with John von Neumann in the 1920s.

The progress in past quarter century has blurred the distinction between these areas: forcing has become an indispensable tool of every set theorist, while descriptive set theory has practically evolved into the study of L(R) under large cardinal assumptions. A Little Set Theory (Never Hurt Anybody) Matthew Saltzman Department of Mathematical Sciences Clemson University Draft: August 19, 2019 1 Introduction The fundamental ideas of set theory and the algebra of sets are probably the most important concepts across all areas of mathematics other than the algebra of real numbers.
