... A morphism f ∈ hom(X , Y ) is an isomorphism if there is a g ∈ hom(Y , X ) such that fg = 1X and gf = 1y . Note that one can provide similar conditions for epi- and mono-morphisms which mirror standard cases of surjections and injections respectively. I only define isomorphisms here because we will ...

That is, the rules of FT are sound if they satisfy this condition: any conclusion we can deduce from a set of premises by means of the rules of FT is in fact a tautological consequence of those premises ...

Taming method in modal logic and mosaic method in temporal logic

The mosaic approach serves as a general method to prove decidability of certain frames of logic. The main key is to show that the existence of a model is equivalent ...

For example, the expression P ∧ (Q ∨ R), read “P and either Q or R,” may be true or false depending on th ...

Curry–Howard correspondence
In programming language theory and proof theory, the Curry–Howard correspondence (also known as the Curry–Howard isomorphism or equivalence, or the proofs-as-programs and propositions- or formulae-as-types interpretation) is the direct relationship between computer programs and mathematical proofs. It is a generalization of a syntactic analogy between systems of formal logic and computational calculi that was first discovered by the American mathematician Haskell Curry and logician William Alvin Howard. It is the link between logic and computation that is usually attributed to Curry and Howard, although the idea is related to the operational interpretation of intuitionistic logic given in various formulations by L. E. J. Brouwer, Arend Heyting and Andrey Kolmogorov (see Brouwer–Heyting–Kolmogorov interpretation) and Stephen Kleene (see Realizability). The relationship has been extended to include category theory as the three-way Curry–Howard–Lambek correspondence.
