Abstract

Only recently the concept of achronal localization has been developed as the adequate frame for the description of the localizability of a relativistic quantum mechanical system. Here covariant achronal localizations are gained out of covariant conserved currents computing their flux passing through achronal surfaces. This general method is applied to the probability density currents with causal kernel regarding the massive scalar boson. As (covariant) achronal localizations correspond one-to-one to (covariant) representations of the causal logic, thus, apparently for the first time, a covariant representation of the causal logic for an elementary relativistic quantum mechanical system has been achieved. Similarly a covariant family of representations of the causal logic is derived from the stress-energy tensor of the massive scalar boson. The construction of an achronal localization from a conserved current relies on a version of the divergence theorem for open sets with almost Lipschitz boundary. This result is stated and proved in this work.
