Title: Connecting Dynamic Epistemic and Temporal Epistemic Logics Authors: H.P. van Ditmarsch, W. van der Hoek, and J. Ruan. Abstract: We give a relation between a logic of knowledge and change, with a semantics on Kripke models, and a logic of knowledge and time, with a semantics on interpreted systems. In particular, given an epistemic state (pointed Kripke [...]

Authors: Hans van Ditmarsch and Ji Ruan Résumé : Dans les puzzles épistémiques les annonces d’ignorance, ou des séquences de tels annonces, souvent résultent en connaissances. Nous présentons le puzzle ‘Quelle Somme ?’, et le modèlisent dans la logique des annonces publiques – un langage logique avec des opérateurs dynamiques et épistémiques. La solution du [...]
