A Modal BI Logic for Dynamic Resource Properties
Résumé
The logic of Bunched implications (BI) and its variants or extensions provide a powerful framework to deal with resources having static properties. In
this paper, we propose a modal extension of BI logic, called DBI, which allows us to deal with dynamic resource properties. After defining a Kripke semantics for DBI, we illustrate the interest of DBI for expressing some dynamic properties and then we propose a labelled tableaux calculus for this logic. This calculus is proved sound and complete w.r.t. the Kripke semantics. Moreover, we also give a method for counter-model generation in this logic.
