• Title: Three Conjectures on Unexpectedeness
• Authors: Giovanni Sileno, Jean-Louis Dessalles
• Abstract summary: This paper lays the groundwork for three theoretical conjectures. First, unexpectedness can be seen as a generalization of Bayes' rule. Second, the frequentist core of unexpectedness can be connected to the function of tracking ergodic properties of the world.

• Abstract: Unexpectedness is a central concept in Simplicity Theory, a theory of cognition relating various inferential processes to the computation of Kolmogorov complexities, rather than probabilities. Its predictive power has been confirmed by several experiments with human subjects, yet its theoretical basis remains largely unexplored: why does it work? This paper lays the groundwork for three theoretical conjectures. First, unexpectedness can be seen as a generalization of Bayes' rule. Second, the frequentist core of unexpectedness can be connected to the function of tracking ergodic properties of the world. Third, unexpectedness can be seen as constituent of various measures of divergence between the entropy of the world (environment) and the variety of the observer (system). The resulting framework hints to research directions that go beyond the division between probabilistic and logical approaches, potentially bringing new insights into the extraction of causal relations, and into the role of descriptive mechanisms in learning.

• Epistemic Boundaries and Quantum Uncertainty: What Local Observers Can (Not) Predict [0.0]
  We argue that post-quantum theories can offer a predictive advantage while conforming to the Born rule on average. We uncover a fascinating possibility: When the assumption of reliable intersubjectivity between different observers is violated, subjective predictive advantage can, in principle, exist. The findings reconcile us to quantum uncertainty as an aspect of limits on Nature's predictability.

  The Prisoner's Dilemma game (PDG) is one of the simple test-beds for the probabilistic nature of the human decision-making process. Quantum probabilistic models can explain this violation as a second-order interference effect. We discuss the role of other quantum information-theoretical quantities, such as quantum entanglement, in the decision-making process.

  We argue in favour of taking Kolmogorov's measure-theoretic axiomatisation of probability as the starting point towards an axiomatisation of causality. Our proposed framework is rigorously grounded in measure theory, but it also sheds light on long-standing limitations of existing frameworks.

  Quantum realms of nonlocality and contextuality are delineated by Bell's theorem and the Kochen-Specker theorem. In this study, we unveil a all-versus-nothing" proof that concurrently illustrates the veracity of these two seminal theorems. Our proof not only substantiates the conflict between quantum mechanics and hidden-variable theories from another perspective, but can also be readily verifiable utilizing the existing linear optics technology.

  Entropic uncertainty relations play an important role in both fundamentals and applications of quantum theory. The current study explores two types of entropic uncertainty relations, preparation and measurement uncertainty relations. It manifests that the entropic structure of uncertainty relations in quantum theory is more universal.

  Three notions are often assumed to be essentially equivalent, representing different facets of the same phenomenon. We analyze them in general Friedmann-Lemaitre- Robertson-Walker space-times through the lens of geometric structures on the classical phase space. The analysis shows that: (i) inflation does not play an essential role; classical behavior can emerge much more generally; (ii) the three notions are conceptually distinct; classicality can emerge in one sense but not in another.

• On the complex behaviour of the density in composite quantum systems [62.997667081978825]
  We study how the probability of presence of a particle is distributed between the two parts of a composite fermionic system. We prove that it is a non-perturbative property and we find out a large/small coupling constant duality. Inspired by the proof of KAM theorem, we are able to deal with this problem by introducing a cut-off in energies that eliminates these small denominators.
