For example, they have been developed for quantificational and modal logics as well.

Proving that GL (the normal modal logic which has the instances of the schema \Box(\Box A\to A)\to\Box A as additional axioms) completely axiomatizes the logic of the provability predicate of Peano Arithmetic.

In an extension, new and different logical constants are added, for instance the "\Box" in modal logic, which stands for "necessarily.

For instance, Gödel showed that all theorems from intuitionistic logic have an equivalent theorem in the classical modal logic S4.

In modal logic the "de re"nbsp;/"nbsp;de dicto distinction" is stated as.

Clarence Irving Lewis credited MacColl's late work on the nature of implication as the source of the basic ideas of Lewis's innovative work in modal logic.

MacColl's work represents one of the first treatments of logical pluralism where he explores the possibilities of modal logic, logic of fiction, connexive logic, many-valued logic and probability logic.

Discusses MacColl's contributions to philosophy of language and logic including modal logic, logic of fictions and modal logic.

Multimodal logic modal logic that has more than one primitive modal operator.

Gabbay, Agi Kurucz, Frank Wolter, Michael Zakharyaschev: Many-dimensional modal logics: theory and applications.

David Makinson is highly regarded for his work on belief revision, uncertain reasoning, and modal logic.

In modal logic and other non-classical logics, he showed how to establish completeness results by adapting the method of maximal consistent set.

He developed the existential graphs until they became another formalism for what are now termed first-order logic and normal modal logic.
