  2. Intuitionistic logic - Wikipedia

    en.wikipedia.org/wiki/Intuitionistic_logic

    Intuitionistic logic is related by duality to a paraconsistent logic known as Brazilian, anti-intuitionistic or dual-intuitionistic logic. [14] The subsystem of intuitionistic logic with the FALSE (resp. NOT-2) axiom removed is known as minimal logic and some differences have been elaborated on above.

  3. Brouwer–Heyting–Kolmogorov interpretation - Wikipedia

    en.wikipedia.org/wiki/Brouwer–Heyting...

    In mathematical logic, the Brouwer–Heyting–Kolmogorov interpretation, or BHK interpretation, of intuitionistic logic was proposed by L. E. J. Brouwer and Arend Heyting, and independently by Andrey Kolmogorov. It is also sometimes called the realizability interpretation, because of the connection with the realizability theory of Stephen ...

  4. Logical intuition - Wikipedia

    en.wikipedia.org/wiki/Logical_intuition

    Logical Intuition, or mathematical intuition or rational intuition, is a series of instinctive foresight, know-how, and savviness often associated with the ability to perceive logical or mathematical truth—and the ability to solve mathematical challenges efficiently. [1]

  5. Intuitionism - Wikipedia

    en.wikipedia.org/wiki/Intuitionism

    The fundamental distinguishing characteristic of intuitionism is its interpretation of what it means for a mathematical statement to be true. In Brouwer's original intuitionism, the truth of a mathematical statement is a subjective claim: a mathematical statement corresponds to a mental construction, and a mathematician can assert the truth of a statement only by verifying the validity of that ...

  6. Indecomposability (intuitionistic logic) - Wikipedia

    en.wikipedia.org/wiki/Indecomposability...

    This principle was established by Brouwer in 1928 [1] using intuitionistic principles, and can also be proven using Church's thesis. The analogous property in classical analysis is the fact that every continuous function from the continuum to {0,1} is constant.

  7. Glossary of logic - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_logic

    A method of mathematical proof used to establish the truth of an infinite number of cases, based on a base case and an inductive step. proof theory The branch of mathematical logic that studies the structure and properties of mathematical proofs, aiming to understand and formalize the process of mathematical reasoning. proof-theoretic consequence

  8. Dialectica interpretation - Wikipedia

    en.wikipedia.org/wiki/Dialectica_interpretation

    In proof theory, the Dialectica interpretation [1] is a proof interpretation of intuitionistic logic (Heyting arithmetic) into a finite type extension of primitive recursive arithmetic, the so-called System T. It was developed by Kurt Gödel to provide a consistency proof of arithmetic.

  9. Peirce's law - Wikipedia

    en.wikipedia.org/wiki/Peirce's_law

    Peirce's law does not hold in intuitionistic logic or intermediate logics and cannot be deduced from the deduction theorem alone. Under the Curry–Howard isomorphism , Peirce's law is the type of continuation operators, e.g. call/cc in Scheme .
