First-Order Hybrid Logic: Introduction and Survey

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


Hybrid logic is an extension of modal logic which allows us to refer explicitly to points of the model in the syntax of formulas. It is easy to justify interest in hybrid logic on applied grounds, with the usefulness of the additional expressive power. For example, when reasoning about time one often wants to build up a series of assertions about what happens at a particular instant, and standard modal formalisms do not allow this.
What is less obvious is that the route hybrid logic takes to overcome this problem often actually improves the behaviour of the underlying modal formalism. For example, it becomes far simpler to formulate proof-systems for hybrid logic, and completeness results can be proved of a generality that is simply not available in modal logic. That is, hybridization is a systematic way of remedying a number of known deficiencies of modal logic.
First-order hybrid logic is obtained by adding first-order machinery to propositional hybrid logic, or equivalently, by adding hybrid-logical machinery to first-order modal logic.
In this short paper we introduce first-order hybrid logic and we give a survey of work in the area.
