  2. List of axioms - Wikipedia

    en.wikipedia.org/wiki/List_of_axioms

    This is a list of axioms as that term is understood in mathematics. In epistemology , the word axiom is understood differently; see axiom and self-evidence . Individual axioms are almost always part of a larger axiomatic system .

  3. Axiom schema of specification - Wikipedia

    en.wikipedia.org/wiki/Axiom_schema_of_specification

    In many popular versions of axiomatic set theory, the axiom schema of specification, [1] also known as the axiom schema of separation (Aussonderungsaxiom), [2] subset axiom [3], axiom of class construction, [4] or axiom schema of restricted comprehension is an axiom schema. Essentially, it says that any definable subclass of a set is a set.

  4. List of first-order theories - Wikipedia

    The axioms for fields, plus axioms for each prime number p stating that if p 1 = 0 (i.e. the field has characteristic p), then every field element has a pth root. Algebraically closed fields of characteristic p. The axioms for fields, plus for every positive n the axiom that all polynomials of degree n have a root, plus axioms fixing the ...

  5. Axiom schema - Wikipedia

    en.wikipedia.org/wiki/Axiom_schema

    An axiom schema is a formula in the metalanguage of an axiomatic system, in which one or more schematic variables appear. These variables, which are metalinguistic constructs, stand for any term or subformula of the system, which may or may not be required to satisfy certain conditions.

  6. Propositional calculus - Wikipedia

    en.wikipedia.org/wiki/Propositional_calculus

    An axiomatic system is a set of axioms or assumptions from which other statements (theorems) are logically derived. [97] In propositional logic, axiomatic systems define a base set of propositions considered to be self-evidently true, and theorems are proved by applying deduction rules to these axioms. [98] See § Syntactic proof via axioms.

  7. Axiomatic foundations of topological spaces - Wikipedia

    If is a set equipped with a mapping satisfying the above properties, then the set of all possible outputs of int satisfies the previous axioms for open sets, and hence defines a topology; it is the unique topology whose associated interior operator coincides with the given int. [28] It follows that on a topological space , all definitions can ...

  8. Foundations of geometry - Wikipedia

    en.wikipedia.org/wiki/Foundations_of_geometry

    In the 1960s a new set of axioms for Euclidean geometry, suitable for American high school geometry courses, was introduced by the School Mathematics Study Group (SMSG), as a part of the New math curricula. This set of axioms follows the Birkhoff model of using the real numbers to gain quick entry into the geometric fundamentals.

  9. Category:Axioms of set theory - Wikipedia

    en.wikipedia.org/wiki/Category:Axioms_of_set_theory

    This category is for axioms in the language of set theory; roughly speaking, ones that "talk about sets". Inclusion in this category does not necessarily imply that the axiom in question is an accepted axiom, or that it is believed to be true in the von Neumann universe of sets.
