Bilattices and the Semantics of Logic Programming
... two and the three valued semantical theories follow easily from work on Belnap’s four-valued version (because two and three valued logics are natural sublogics of the four-valued logic). And this is not unique to the four-valued case; with no more work similar results can be established for bilattic ...

CHAPTER 9 Two Proofs of Completeness Theorem 1 Classical

It is, as the proof of Deduction Theorem, a fully constructive proof. The technique it uses, because of its specifics can’t even be u ...

Theories of arithmetics in finite models
... We investigate theories of initial segments of the standard models for arithmetics. It is easy to see that if the ordering relation is definable in the standard model then the decidability results can be transferred from the infinite model into the finite models. On the contrary we show that the Σ2 ...
