Games in Minkowski Spacetime
Ghislain Fourny
This paper contributes a new class of games called spacetime games with perfect information. In spacetime games, the agents make decisions at various positions in Minkowski spaceti…
Perfect Prediction in Minkowski Spacetime: Perfectly Transparent Equilibrium for Dynamic Games with Imperfect Information
Ghislain Fourny
The assumptions of necessary rationality and necessary knowledge of strategies, also known as perfect prediction, lead to at most one surviving outcome, immune to the knowledge tha…
Kripke Semantics of the Perfectly Transparent Equilibrium
Ghislain Fourny
The Perfectly Transparent Equilibrium is algorithmically defined, for any game in normal form with perfect information and no ties, as the iterated deletion of non-individually-rat…
Perfect Prediction in Normal Form: Superrational Thinking Extended to Non-Symmetric Games
Ghislain Fourny
This paper introduces a new solution concept for non-cooperative games in normal form with no ties and pure strategies: the Perfectly Transparent Equilibrium. The players are ratio…
Common Counterfactual Belief of Rationality Subsumes Superrationality On Symmetric Games
Ghislain Fourny
This paper shows that, for symmetric games in normal form, strategy profiles that satisfy Hofstadter's Superrationality criterion also satisfy both of Halpern's and Pass's criteria…
On the Importance of Correlations in Rational Choice: A Case for Non-Nashian Game Theory
Ghislain Fourny
The Nash equilibrium paradigm, and Rational Choice Theory in general, rely on agents acting independently from each other. This note shows how this assumption is crucial in the def…
Perfect Prediction Equilibrium
Ghislain Fourny, Stéphane Reiche, Jean-Pierre Dupuy
In the framework of finite games in extensive form with perfect information and strict preferences, this paper introduces a new equilibrium concept: the Perfect Prediction Equilibr…
