M. Vujicic et al., TOWARDS A CAUSAL SUBQUANTUM THEORY - A CONTEXTUAL C-ASTERISK-ALGEBRAIC APPROACH, Journal of physics. A, mathematical and general, 27(12), 1994, pp. 4221-4234
Quantum mechanics is enlarged into a contextual subquantum model, with
the purpose of describing causally individual quantum systems. This m
odel is based on the spectra of the quantum-mechanical observables. A
C-algebraic generalization of this model is presented. Various physic
ally interesting aspects of the constructed subquantum model are discu
ssed.
