Categorical proof theory of classical propositional calculus
نویسندگان
چکیده
We investigate semantics for classical proof based on the sequent calculus. We show that the propositional connectives are not quite well-behaved from a traditional categorical perspective, and give a more refined, but necessarily complex, analysis of how connectives may be characterised abstractly. Finally we explain the consequences of insisting on more familiar categorical behaviour.

An Institutional View on Categorical Logic
We introduce a generic notion of categorical propositional logic and provide a construction of a preorder-enriched institution out of such a logic, following the Curry-Howard-Tait paradigm. The logics are specified as theories of a meta-logic within the logical framework LF such that institution comorphisms are obtained from theory morphisms of the metalogic. We prove several logic-independent ...
متن کاملA Semantic View of Classical Proofs: Type-Theoretic, Categorical, and Denotational Characterizations (Preliminary Extended Abstract)
Classical logic is one of the best examples of a mathematical theory that is truly useful to computer science. Hardware and software engineers apply the theory routinely. Yet from a foundational standpoint, there are aspects of classical logic that are problematic. Unlike intuitionistic logic, classical logic is often held to be non-constructive, and so, is said to admit no proof semantics. To ...
متن کاملTruth Values and Connectives in Some Non-Classical Logics
The question as to whether the propositional logic of Heyting, which was a formalization of Brouwer's intuitionistic logic, is finitely many valued or not, was open for a while (the question was asked by Hahn). Kurt Gödel (1932) introduced an infinite decreasing chain of intermediate logics, which are known nowadays as Gödel logics, for showing that the intuitionistic logic is not finitely (man...
متن کاملNaming Proofs in Classical Propositional Logic
We present a theory of proof denotations in classical propositional logic. The abstract definition is in terms of a semiring of weights, and two concrete instances are explored. With the Boolean semiring we get a theory of classical proof nets, with a geometric correctness criterion, a sequentialization theorem, and a strongly normalizing cut-elimination procedure. This gives us a “Boolean” cat...
متن کاملTowards a Theory of Proofs of Classical Logic
The questions “What is a proof?” and “When are two proofs the same?” are fundamentalfor proof theory. But for the most prominent logic, Boolean (or classical) propositionallogic, we still have no satisfactory answers.This is embarrassing not only for proof theory itself, but also for computer science,where classical propositional logic plays a major role in automated reasoning a...
