WebApr 14, 2024 · The completeness of tableaux systems is usually proved by defining a notion of a Hintikka set: a saturated set of (labelled) formulae (and possibly constraints) that specifies a term model of the logic. The existence of a Hintikka set is then shown to follow from non-existence of a tableau proof. WebIf a formula in the set has a principle operator that is of "disjuntive-type", then at least one of its two operands appears in the set. The exact meaning of "conjuctive-type" and "disjunctive-type" is defined by the method of semantic tableaux.

WebJan 4, 2006 · Von Wright's insights were extended by Jaakko Hintikka in his book Knowledge and Belief: An Introduction to the Logic of the Two Notions (1962). In the 1980s and 1990s, epistemic logicians focused on the logical properties of systems containing groups of knowers and later still on the epistemic features of so-called "multi-modal" …

WebHere, Hintikka sets provide a useful stepping stone. These can be seen as characterizations of the MCSs based on simple subformula conditions rather than via the calculus. We then prove that every Hintikka set gives rise to a satisfying model and that MCSs are Hintikka sets. Now, assume a valid formula cannot be derived. regain my facebookWebCompletenessproof.
