    "abstract": "The relativistic phase-space representation by means of the usual position\nand momentum operators for a class of observables with Weyl symbols independent\nof charge variable (i.e. with any combination of position and momentum) is\nproposed. The dynamical equation coincides with its analogue in the non-local\ntheory (generalization of the Newton-Wigner position operator approach) under\nconditions when particles creation is impossible. Differences reveal themselves\nin specific constraints on possible initial conditions.",
