The Space-time Origin of Quantum Mechanics: Covering Law

Lorentz covariance imposed upon a quantum logic of local propositions for which all observers can consistently maintain state collapse descriptions, implies a condition on space-like separated propositions that if imposed on generally commuting ones would lead to the covering law, and hence to a hilbert-space model for the logic. Such a generalization can be argued if state preparation can be conditioned to space-like separated events using EPR-type correlations. This suggests that the covering law is related to space-time structure, though a final understanding of it, through a self-consistency requirement, will probably require quantum space-time.
