• Title: Let the Mathematics of Quantum Speak: Allowed and Unallowed Logic
• Authors: Eliahu Levy
• Abstract summary: The mathematics/formalism of quantum, compared with classical, physics, may be fairly basically characterized by non-commutative algebras replacing commutative. One may have the latter only in a haven' of approximately commutative algebras of quasi-classical macroscopic observables', and moreover that yes-no actual world' would plainly be an extra ingredient' to the base quantum theory itself.

• Abstract: Some notes about quantum physics, an interpretation if one wishes, are put forward, insisting on `closely following the mathematics/formalism, the `nuts and bolts of what quantum physics says'. These, basically well-known, issues seem to highlight some rather bold points about the `logic' aspect in quantum physics, necessarily restricting when and which logic may be admissible. And one may understand why that path is hardly followed in the literature. The mathematics/formalism of quantum, compared with classical, physics, may be fairly basically characterized by non-commutative algebras replacing commutative. These classically appearing, in fact, in dealing with systems of possibilities (say, all possible planetary motions under gravity of which one is the actual one). In particular, contrary to too common usage, the quantum non-commutativity should make it impossible to simply `transcend' the `system of possibilities' aspect into a `yes-no' logic essential for an `actual world'. One may have the latter only in a `haven' of approximately commutative algebras of `quasi-classical macroscopic observables', and moreover that `yes-no actual world' would plainly be an `extra ingredient' to the base quantum theory itself.

  I present a simple baby-steps reconstruction of quantum mechanics as a fully classical theory. Despite its simplicity and minimalism of radical concepts, this is not a toy model, being equivalent with quantum field theory.

• Postulating the Unicity of the Macroscopic Physical World [0.0]
  We argue that the unicity of the macroscopic world is a fundamental postulate of physics, rather than an issue that must be mathematically justified or demonstrated. This is made possible by using general operator algebras to extend the mathematical description of the physical world towards macroscopic systems.

  We show that quantum theory requires the abandonment of classical logic. We find an inevitable generalization of classical logic. We illustrate this by applying the logic to explain puzzling results in quantum cognition.

• Quantum indistinguishability through exchangeable desirable gambles [69.62715388742298]
  Two particles are identical if all their intrinsic properties, such as spin and charge, are the same. Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles. We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.

• Symmetries in Foundation of Quantum Theory and Mathematics [0.0]
  We consider finite quantum theory (FQT) where states are elements of a space over a finite ring or field with characteristic $p$ and operators of physical quantities act in this space. We prove that, with the same approach to symmetry, FQT and finite mathematics are more general than standard quantum theory and classical mathematics.
