Preface

This volume consists of papers presented at the Seventeenth Conference on Theoretical Aspects of Rationality and Knowledge (TARK) held at the Université Toulouse in Toulouse, France, from July 17-19, 2019.

As with all previous TARK conferences, this one was a lively interdisciplinary event. It brought together researchers from a wide variety of fields, including Computer Science (especially Artificial Intelligence, and CS Theory), Economics (especially Decision Theory, Game Theory, and Social Choice Theory), Philosophy (especially Philosophical Logic), and Psychology, in order to further understand the issues involving reasoning about rationality and knowledge. The mixing and blending of fields is evident from the papers in this volume: several of them are contributions to more than one of the fields listed above, and all of them were prepared and presented to talk across boundaries.

The conference received 53 submitted abstracts. It accepted 25 papers, of which 17 were presented as talks and 8 as posters. Decisions were not easy. They involved extensive discussions by the Program Committee. I thank all the members of that committee: Pierpaolo Battigalli, Adam Bjorndahl, Giacomo Bonanno, Amanda Friedenberg, Filomena Garcia, Valentin Goranko, Umberto Grandi, Joseph Halpern, Aviad Heifetz, Jérôme Lang, Emiliano Lorini, Eric Pacuit, Andrés Perea, Francesca Poggiolesi, Ricardo Pucella, R. Ramanujam, and Sonja Smets.

I want to thank everyone who submitted papers to the meeting.

The meeting was enriched by our invited speakers: Ingela Alger (CNRS), Vincent Conitzer (Duke University), and Brian Hill (CNRS, HEC Paris). My thanks to them all for enlivening TARK.

The meeting would not have been possible without our local organizers. Chief among them were the Organisation Co-chairs: Andreas Herzig, Emiliano Lorini, and Umberto Grandi. They had the able help of an organizing committee which included Dominique Longin, Fabian Romero, Jorge Fernandez, Saul Fernandez, Munyque Mittelmann, Elise Perrrotin, and Julien Vianey. I am very grateful to all of them.

I thank EasyChair for making its conference management system available. I also thank Rob van Glabbeek and the EPTCS staff for all their help with this volume.

TARK began with a meeting in Monterey California in 1986, and this volume has the papers from TARK XVII. Some topics presented at TARK in the intervening years were, and still are, important in my intellectual life. I was really pleased to chair the PC of TARK this year. Joe Halpern has my very warm thanks, not only for keeping the meeting strong for decades, but also for help and advice on this meeting.
