This is a list of mathematical logic topics. For traditional syllogistic logic, see the list of topics in logic . See also the list of computability and complexity topics for more theory of algorithms .
In logic, proof by contradiction is a form of proof that establishes the truth or the validity of a proposition by showing that assuming the proposition to be false leads to a contradiction. Although it is quite freely used in mathematical proofs, not every school of mathematical thought accepts this kind of nonconstructive proof as universally ...

Hilbert's 1927, Based on an earlier 1925 "foundations" lecture (pp. 367–392), presents his 17 axioms—axioms of implication #1-4, axioms about & and V #5-10, axioms of negation #11-12, his logical ε-axiom #13, axioms of equality #14-15, and axioms of number #16-17—along with the other necessary elements of his Formalist "proof theory"—e ...
In mathematics and logic, a value or element that is mapped to itself by a particular function or operation. forced march sorites A type of sorites paradox involving a series of incremental steps or changes that lead to a contradiction, challenging the precision of vague predicates by forcing a march from one end of a spectrum to another.

Jankov logic (KC) is an extension of intuitionistic logic, which can be axiomatized by the intuitionistic axiom system plus the axiom [13] ¬ A ∨ ¬ ¬ A . {\displaystyle \neg A\lor \neg \neg A.} Gödel–Dummett logic (LC) can be axiomatized over intuitionistic logic by adding the axiom [ 13 ]
To change this template's initial visibility, the |state= parameter may be used: {{Mathematical logic | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Mathematical logic | state = expanded}} will show the template expanded, i.e. fully visible.
