Dynamics and predictions in the co-event interpretation

Sorkin has introduced a new, observer independent, interpretation of quantum mechanics that can give a successful realist account of the ‘quantum micro-world’ as well as explaining how classicality emerges at the level of
observable events for a range of systems including single time ‘Copenhagen measurements’. This ‘co-event interpretation’ presents us with a new ontology,
in which a single ‘co-event’ is real. A new ontology necessitates a review of the dynamical and predictive mechanism of a theory, and in this paper we begin the
process by exploring means of expressing the dynamical and predictive content of histories theories in terms of co-events.
