Sheaf Logic, Quantum Set Theory and the Interpretation of Quantum Mechanics
Based on the Sheaf Logic approach to set theoretic forcing, a hierarchy of
Quantum Variable Sets is constructed which generalizes and simplifies the
analogous construction developed by Takeuti on boolean valued models of set
theory. Over this model two alternative proofs of Takeuti's correspondence,
between self adjoint operators and the real numbers of the model, are given.
This approach results to be more constructive showing a direct relation with
the Gelfand representation theorem, revealing also the importance of these
results with respect to the interpretation of Quantum Mechanics in close
connection with the Deutsch-Everett multiversal interpretation. Finally, it is
shown how in this context the notion of genericity and the corresponding
generic model theorem can help to explain the emergence of classicality also in
connection with the Deutsch- Everett perspective.Comment: 34 pages, 2 figure
Boolean Coverings of Quantum Observable Structure: A Setting for an Abstract Differential Geometric Mechanism
We develop the idea of employing localization systems of Boolean coverings,
associated with measurement situations, in order to comprehend structures of
Quantum Observables. In this manner, Boolean domain observables constitute
structure sheaves of coordinatization coefficients in the attempt to probe the
Quantum world. Interpretational aspects of the proposed scheme are discussed
with respect to a functorial formulation of information exchange, as well as,
quantum logical considerations. Finally, the sheaf theoretical construction
suggests an opearationally intuitive method to develop differential geometric
concepts in the quantum regime.Comment: 25 pages, Late
