Vor 4 Tagen · Constructive set theory. Axiomatic constructive set theory is an approach to mathematical constructivism following the program of axiomatic set theory . The same first-order language with " " and " " of classical set theory is usually used, so this is not to be confused with a constructive types approach.
Vor 22 Stunden · Binary relations are used in many branches of mathematics to model a wide variety of concepts. These include, among others: the "is greater than", "is equal to", and "divides" relations in arithmetic; the "is congruent to" relation in geometry; the "is adjacent to" relation in graph theory;
Vor einem Tag · For example, Von Neumann–Bernays–Gödel set theory, is an extension of the set theory in which the collection of all sets is a class. This theory includes the replacement axiom, which may be stated as: If X is a set and F is a function, then F[X] is a set.
Vor 2 Tagen · His results were foundational for all the central areas of contemporary logic: set theory, model theory, computability theory, and proof theory. We teach a variety of courses in logic. Current research in our key research area mainly focuses on set theory and model theory .

Vor 4 Tagen · Number theory is the study of properties of the integers. Because of the fundamental nature of the integers in mathematics, and the fundamental nature of mathematics in science, the famous mathematician and physicist Gauss wrote: "Mathematics is the queen of the sciences, and number theory is the queen of mathematics."
