Extending quantum theory with AI-assisted deterministic game theory

Florian Pauschitz, Ben Moseley, Ghislain Fourny

We present an AI-assisted framework for predicting individual runs of complex quantum experiments, including contextuality and causality (adaptive measurements), within our long-te…

Spacetime games subsume causal contextuality scenarios

Ghislain Fourny

We show that a category of causal contextuality scenarios with no cycles, unique causal bridges, and causally secured covers is equivalent to a category containing a subclass of th…

Space-time-hap: a coordinate system for the multiverse and its application to show that free choice is observer-dependent

Ghislain Fourny

This note proposes a paradigm and coordinate system that extends flat, four-dimensional Minkowski spacetime to a broader framework that identifies an event not only in space and in…

RumbleML: program the lakehouse with JSONiq

Ghislain Fourny, David Dao, Can Berker Cikis +2

Lakehouse systems have reached in the past few years unprecedented size and heterogeneity and have been embraced by many industry players. However, they are often difficult to use…

Nashian game theory is incompatible with quantum physics

Michal Baczyk, Ghislain Fourny

We suggest to look at quantum measurement outcomes not through the lens of probability theory, but instead through decision theory. We introduce an original game-theoretical framew…

The Future of Quantum Theory: A Way Out of the Impasse

Ghislain Fourny

In this letter, we point to three widely accepted challenges that the quantum theory, quantum information, and quantum foundations communities are currently facing: indeterminism,…

Evaluating Query Languages and Systems for High-Energy Physics Data [Extended Version]

Dan Graur, Ingo Müller, Mason Proffitt +3

In the domain of high-energy physics (HEP), query languages in general and SQL in particular have found limited acceptance. This is surprising since HEP data analysis matches the S…

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…

Rumble: Data Independence for Large Messy Data Sets

Ingo Müller, Ghislain Fourny, Stefan Irimescu +2

This paper introduces Rumble, a query execution engine for large, heterogeneous, and nested collections of JSON objects built on top of Apache Spark. While data sets of this type a…

Contingent Free Choice: On Extending Quantum Theory to a Contextual, Deterministic Theory With Improved Predictive Power

Ghislain Fourny

The non-extensibility of quantum theory into a theory with improved predictive power is based on a strong assumption of independent free choice, in which the physicists pick a meas…

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…

decimalInfinite: All Decimals In Bits, No Loss, Same Order, Simple

Ghislain Fourny

This paper introduces a binary encoding that supports arbitrarily large, small and precise decimals. It completely preserves information and order. It does not rely on any arbitrar…

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…
