 Let us come back to the relativistic DRP. Some important changes have occurred quite recently. Tumulka (2006a) succeeded in proposing a relativistic version of the GRW theory for N non-interacting distinguishable particles, based on the consideration of a multi-time wavefunction whose evolution is governed by Dirac like equations and adopts as its Primitive Ontology (see the next section) the one which attaches a primary role to the space and time points at which spontaneous localizations occur, as originally suggested by Bell (1987). To our knowledge this represents the first proposal of a relativistic dynamical reduction mechanism, which satisfies all relativistic requirements. In particular it is free from divergences and foliation independent. However, it is formulated only for systems containing a fixed number of noninteracting fermions.
