  The TARK conference (Theoretical Aspects of Rationality and Knowledge) is a
conference that aims to bring together researchers from a wide variety of
fields, including computer science, artificial intelligence, game theory,
decision theory, philosophy, logic, linguistics, and cognitive science. Its
goal is to further our understanding of interdisciplinary issues involving
reasoning about rationality and knowledge.
  Previous conferences have been held biennially around the world since 1986,
on the initiative of Joe Halpern (Cornell University). Topics of interest
include, but are not limited to, semantic models for knowledge, belief,
awareness and uncertainty, bounded rationality and resource-bounded reasoning,
commonsense epistemic reasoning, epistemic logic, epistemic game theory,
knowledge and action, applications of reasoning about knowledge and other
mental states, belief revision, computational social choice, algorithmic game
theory, and foundations of multi-agent systems. Information about TARK,
including conference proceedings, is available at http://www.tark.org/
  These proceedings contain the papers that have been accepted for presentation
at the Nineteenth Conference on Theoretical Aspects of Rationality and
Knowledge (TARK 2023), held between June 28 and June 30, 2023, at the
University of Oxford, United Kingdom. The conference website can be found at
