Bilattices and the Semantics of Logic Programming
... M. Ginsberg has invented the elegant notion of bilattice ([14], [15]), which deals with precisely this issue. We reserve the definition till later on, but for motivation we note: Belnap’s four valued logic constitutes the simplest bilattice; a natural bilattice can be constructed based on any ‘reaso ...

An Introduction to Proof Theory - UCSD Mathematics
... In practice, social proofs and formal proofs are very closely related. Firstly, a formal proof can serve as a social proof (although it may be very tedious and unintuitive) provided it is formalized in a proof system whose validity is trusted. Secondly, the standards for social proofs are sufficient ...

Negation goes beyond monotone inductive definitions: with negated subgoals, the function φ above may not be monotone. However, perhaps the database can be partitioned into ...

The paper is divided into the following sections: – In section 1, after introducing some terminology about directed acyclic graphs we give some background on the syntax of multiplicative linear logic (MLL) and proof nets. We revise the notion of proof nets, in order to be able to add sequential edge ...

Modal Logic for Artificial Intelligence

If we know what the truth value is of A and B, then we know what the truth value is of ‘A or B’, ‘not A’, and so on. Proof-theoretic approac ...
