    "abstract": "The second-order partial derivatives of the Coulomb potential of a point\ncharge can be regularized using the Coulomb potential of a charge of the oblate\nspheroidal shape that a moving rest-frame-spherical charge acquires by the\nLorentz contraction. This `physical\u0027 regularization is shown to be fully\nequivalent to the standard delta-function identity involving these derivatives.",
