Intuitionistic Logic
... A proof of A∧B is simply a pair of proofs a and b of A and B. For convenience we introduce a a notation for the pairing of constructions, and for the inverses (projections); (a, b) denotes the pairing of a and b, and (c)0 ,(c)1 , are the first and second projection of c. Now, the proof of a disjunc ...

... A proposition (p, q, r, …) is simply a statement (i.e., a declarative sentence) with a definite meaning, having a truth value that’s either true (T) or false (F) (never both, neither, or somewhere in between). (However, you might not know the actual truth value, and it might be situation-dependent.) ...

... Constructivism is a point of view concerning the concepts and methods used in mathematical proofs, with preference towards constructive concepts and methods. It emerged in the late 19th century, as a response to the increasing use of abstracts concepts and methods in proofs in mathematics. Kronecker ...
