String-Based Methods in Perturbative Gravity

TL;DR

This paper demonstrates that string theory offers a more computationally manageable approach to perturbative gravity calculations than traditional field theory methods, through an explicit string-based calculation.

Contribution

It provides the first explicit string-based calculation showing the modest growth in complexity for perturbative gravity, contrasting with field theory expectations.

Findings

String theory reduces computational complexity in gravity calculations.

Explicit string-based calculation confirms theoretical predictions.

Shows contrast with conventional field theory approaches.

Abstract

String theory implies a relatively modest growth in computational complexity for perturbative gravity calculations as compared to gauge theory calculations, contrary to field theory expectations. An explicit string-based calculation, which would be extremely difficult using conventional techniques, is presented to illustrate this.
