Regularisation of classical self interaction in strings

TL;DR

This paper extends a regularisation method for classical self-interaction from electromagnetism to gravitation, providing a unified approach that can be viewed as a form of renormalisation.

Contribution

It introduces a generalized regularisation technique applicable to gravitational self-interactions, building upon previous electromagnetic methods.

Findings

The method successfully regularizes gravitational self-interaction.

The approach unifies electromagnetic and gravitational regularisation techniques.

It offers a new perspective on renormalisation in classical field theories.

Abstract

A general method of regularisation of classical self interaction in strings is extended from the electromagnetic case (for which it was originally developed) to the gravitation case, for which the result can also be represented as a renormalisation.
