Coalgebras and Modal Logic

Publisher: ESSLLI 2002
Number of pages: 100
Whereas algebras are used to model abstract data types, coalgebras are used to model dynamic, state based systems. One of the achievements of the theory of coalgebras is to make clear that these seemingly different areas are related by duality. The aim of the course is to explain this duality and to develop some consquences. In particular, recent research lead to the insight that modal logic is dual to equational logic.

This is a text for dedicated undergraduates with no previous experience in modal logic. The book should prepare people for reading advanced texts in modal logic, such as Goldblatt, Chellas, Hughes and Cresswell, and van Benthem.

This Handbook documents the current state of modal logic, a lively area of logical research which was born in philosophy, but which has since made its way into mathematics, linguistics, computer science, AI, and even economic game theory.
