摘要：

The classical linearised gravitational self interaction of a Nambu-Goto string is examined in four spacetime dimensions. Using a conveniently gauge independent tensorial treatment, the divergent part of the self-force is shown to be exactly zero. This is due to cancellation by a contribution that was neglected in the previous treatments. This result has implications for many applications. (C) 1998 Published by Elsevier Science B.V.
