  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.

    en.wikipedia.org/wiki/Occam's_razor

    Rather than depend on provability of these axioms, science depends on the fact that they have not been objectively falsified. Occam's razor and parsimony support, but do not prove, these axioms of science. The general principle of science is that theories (or models) of natural law must be consistent with repeatable experimental observations.

    2. Zermelo−Fraenkel set theory is the standard system of axioms for set theory 3. Zermelo set theory is similar to the usual Zermelo-Fraenkel set theory, but without the axioms of replacement and foundation 4. Zermelo's well-ordering theorem states that every set can be well ordered ZF Zermelo−Fraenkel set theory without the axiom of choice ZFA

  6. Kuratowski closure axioms - Wikipedia

    en.wikipedia.org/wiki/Kuratowski_closure_axioms

    Notice that axioms [K1]–[K4] may be adapted to define an abstract unary operation : on a general bounded lattice (,,,,), by formally substituting set-theoretic inclusion with the partial order associated to the lattice, set-theoretic union with the join operation, and set-theoretic intersections with the meet operation; similarly for axioms ...

    In this sense, the continuum hypothesis is undecidable, and it is the most widely known example of a natural statement that is independent from the standard ZF axioms of set theory. For his result on the continuum hypothesis, Cohen won the Fields Medal in mathematics in 1966, and also the National Medal of Science in 1967. [ 12 ]

  8. Hilbert system - Wikipedia

    en.wikipedia.org/wiki/Hilbert_system

    Hilbert systems are characterized by the use of numerous schemas of logical axioms. An axiom schema is an infinite set of axioms obtained by substituting all formulas of some form into a specific pattern. The set of logical axioms includes not only those axioms generated from this pattern, but also any generalization of one of those axioms.

    The Unger translation differs from the Townsend translation with respect to the axioms in the following ways: Old axiom II.4 is renamed as Theorem 5 and moved. Old axiom II.5 (Pasch's Axiom) is renumbered as II.4. V.2, the Axiom of Line Completeness, replaced: Axiom of completeness. To a system of points, straight lines, and planes, it is ...
