Tableau Systems for Some Ivlev-Like (Quantified) Modal Logicsontinuing our previous work on Ivlev-like non-normal modal logics with non-deterministic semantics, we present in this paper tableau systems for ., . ., the non-normal versions of ., . and ., respectively, as well as for their corresponding first-order extensions ., . and .. We also prove that the m

Plurivaluationism, Semantic Nondeterminism and CommunicationMore specifically, the paper contrasts two views in the literature of what happens when semantic values are constrained to a range without a particular member of the range being determined as the uniquely correct value. One view—semantic nondeterminism—holds that a single, unique value is chosen non

Algebras and Relational Frames for Gödel Modal Logic and Some of its Extensionslational semantics for Gödel modal logics that leverages on the duality between finite Gödel algebras and finite forests, i.e. finite posets whose principal downsets are totally ordered. We consider different subvarieties of the basic variety . of Gödel algebras with two modal operators (GAOs for sh

On Ivlev’s Semantics for Modalityodality even before Kripke. Jan Łukasiewicz gave two accounts, and, in this paper, we focus on the second account which turned out to be an approach through many-valued semantics. This attempt is now evaluated as a failed project after an observation by Josep Maria Font and Petr Hájek. Recently, Jea

Efficient Reasoning About Knowledge and Common Knowledgethat, there can be observation about other agents’ observations and there can be joint observation. We prove that the resulting Epistemic Logic of Observation (EL-O) can be identified with a fragment of epistemic logic: boolean combinations of ‘knowing-whether’ atoms, that is, sequences of ‘individu
