Modal Logic
Dr. Jakob Piribauer
SWS: (2/2/0), in English
Description
Modalities are expressions that quantify the truth of a statement, e.g., 'possibly' and 'necessarily'. Modal logics are simple, yet expressive, formalisms that incorporate such modalities. The incorporated modalities offer a wide variety of possible readings such as temporal readings ('at some point in the future …'), epistemic readings ('the agent knows that …'), or readings talking about the dynamics of programs ('there is an execution of program P after which …'). Therefore, modal logics are applicable to various application domains and play an important role in computer science, philosophy, mathematics, and linguistics among others.
This course provides an introduction to the main concepts of modal logic with a focus on its role in computer science. It covers:
- syntax and semantics of modal logics,
- Kripke structures and Kripke frames,
- bisimulations,
- translations to first-order logic,
- frame definability,
- soundness and completeness results,
- complexity and decidability results,
- propositional dynamic logic.
Literature
The course follows the book "Modal logic (Fourth printing with corrections)", Patrick Blackburn, Maarten de Rijke, Yde Venema; Cambridge University Press, 2010.
This book is available online via the SLUB.
Registration
Enrolling via OPAL is required until October 16th 2023.
