In recent years combinations of tense and modality have moved intothe focus of logical research. From a philosophical point of view, logical systems combining tense and modality are of interest ...

Technical Terms Modal logic: A branch of logic that extends classical propositional and predicate logic to include operators expressing modality, such as necessity and possibility.

This field harnesses formal logics – from classical propositional and predicate logics to nonmonotonic frameworks such as answer set programming – to enable rigorous inference, update, and ...
