    Notes: [Auszug] METHODS are now available for the estimation of several important body constituents by nondestructive testing which can be applied to the living subject. Total-body water can be determined by the method of isotopic dilution using deuterium oxide or tritium oxide as the tracer. Estimates of the ...

    Quantum logic, state space geometry and operator algebras (1984)

    Notes: Abstract The problem of characterising those quantum logics which can be identified with the lattice of projections in a JBW-algebra or a von Neumann algebra is considered. For quantum logics which satisfy the countable chain condition and which have no TypeI 2 part, a characterisation in terms of geometric properties of the quantum state space is given.

    Notes: Abstract A problem of Mackey for von Neumann algebras has been settled by the conjunction of the early work of Gleason and the recent advances of Christensen and Yeadon. We show that Mackey's conjecture holds in much greater generality. LetA be a JBW-algebra and letL be the lattice of all projections inA. A quantum measure onL is a countably additive map,m, fromL into the real numbers. Our results imply thatm always has a unique extension to a bounded linear functional onA, provided thatA has no TypeI 2 direct summand.

    Quantum logics and convex geometry (1985)

    Notes: Abstract The main result is a representation theorem which shows that, for a large class of quantum logics, a quantum logic,Q, is isomorphic to the lattice of projective faces in a suitable convex setK. As an application we extend our earlier results [4], which, subject to countability conditions, gave a geometric characterization of those quantum logics which are isomorphic to the projection lattice of a von Neumann algebra or aJ B W-algebra.
