Abstract

This paper will discuss the representation of properties in two modal interpretations of quantum mechanics: Richard Healey’s interactive interpretation (Healey, 1989) and the Kochen-Dieks-Clifton (KDC) interpretation, as presented in Clifton (1995). Like many realist interpretations, these interpretations take the set of a system’s dynamical properties, ordered by some appropriate ordering relation, to be isomorphic to the set of projection operators in the Hilbert space associated with the system. The two interpretations share a further similarity: as i will discuss in Section 3, they both assign to the biorthogonal decomposition theorem (or to a generalization of that theorem) a central role in determining which of a system’s properties are possessed at a given time.
