要旨:
We present an original approach to compute the electromagnetic self force
acting on a static charge in Kerr spacetime. Our approach is based on an
improved version of the Janis-Newman algorithm and extends its range of
applicability. It leads to a closed expression which generalizes the existing
one and, since it does not involve the electromagnetic potential, it simplifies
the calculation of the self force.
