The Substantial Role of Weyl Symmetry in Deriving General Relativity from String Theory

Dougherty, John (2021): The Substantial Role of Weyl Symmetry in Deriving General Relativity from String Theory. In: Philosophy of Science, Bd. 88, Nr. 5: S. 1149-1160

Abstract

String theory reduces to general relativity in appropriate regimes. Huggett and Vistarini have given an account of this reduction that includes a deflationary thesis about symmetry: although the usual derivation of general relativity from string theory appeals to a premise about the theory's symmetry, Huggett and Vistarini argue that this premise plays no logical role. In this article I disagree with their deflationary thesis and argue that their analysis is based on a popular but flawed conception of the interaction between symmetry and quantization. I argue that a better conception recognizes a distinction between ordinary, broken, and anomalous symmetries.
