Ninth conference on

Theoretical Aspects of Rationality and Knowledge



June 20-22, 2003

Bloomington, Indiana, USA

About the Conference

The mission of the TARK conferences is to bring together researchers from a wide variety of fields – including Artificial Intelligence, Cryptography, Distributed Computing, Economics and Game Theory, Linguistics, Philosophy, and Psychology – in order to further our understanding of interdisciplinary issues involving reasoning about rationality and knowledge. Topics of interest include, but are not limited to, semantic models for knowledge, belief, and uncertainty, bounded rationality and resource-bounded reasoning, commonsense epistemic reasoning, epistemic logic, knowledge and action, applications of reasoning about knowledge and other mental states, belief revision, and foundations of multi-agent systems. TARK IX will be coordinated with the the 2nd North American Summer School in Logic, Language and Information (NASSLLI 2003; NASSLLI will offer TARK-related courses, and some talks will be shared by TARK and NASSLLI, allowing for interaction between prominent researchers and research students.
