Abstract

The structure of the spaces of propositions and decoherence functions in the consistent-histories approach to generalized quantum theory is outlined. It is shown that although the space of decoherence functions is convex, there are no pure decoherence functions. A definition of information-entropy is described which no needs no a priori notion of time.
