    "abstract": "The conserved probability densities (attributed to the conserved currents\nderived from relativistic wave equations) should be non-negative and the\nintegral of them over an entire hypersurface should be equal to one. To satisfy\nthese requirements in a covariant manner, the foliation of spacetime must be\nsuch that each integral curve of the current crosses each hypersurface of the\nfoliation once and only once. In some cases, it is necessary to use\nhypersurfaces that are not spacelike everywhere. The generalization to the\nmany-particle case is also possible.",
